Before placing my previous coral order I had expressed an interest in purchasing a frag of a different gorgonian from a fellow reefer. Unfortunately I was a little too slow off the mark and the frag sold to someone else. The very next day I discovered the purple gorgonian online so I ordered that instead but before it had even been delivered the kindly reefer contacted me and asked if I still wanted a frag of his gorgonian. He could take a small cutting just for me, naturally I said yes, I can always find a spot for something small lol. In addition he also offered to take a frag of his Chilli coral which was another species I'd always wanted to keep and had been searching for.
Here is the gorgonian settling in on the frag rack, 3 days after delivery. I'm not sure of the species, it could possibly be Leptogorgia chilensis.
Here it is fixed in position with the Coco worm for size reference behind.
It seems to be doing OK so far, the polyps are extended for most of the day but I am yet to notice any growth or encrustation at the base. Here it is again 11 days later (you can see the Coco worm has been busy at the back).
As for the Chilli coral, Nephthyigorgia sp. It's not much to look at when closed up but is really lovely when the polyps extend, here is how it looked after introduction with some hermit crabs giving it the once over.
These corals are non photosynthetic and need to be kept out of the light, hanging upside down in caves. I chose the best spot I had available, semi shaded but still able to be viewed. Hanging any coral upside down is not the easiest thing to accomplish. I had to use a fair bit of putty and it's not an attractive look but hopefully it will be hidden by coralline algae eventually. Thank fully the coral hasn't fallen down... yet!
In addition to the Pebble crab (RIP) I also received a commensal crab and a gorgonian.
The crab was a coral crab, Trapezia cymodoce. In the wild these crustaceans live in association with SPS corals, defending them against predators and feeding on the mucus produced by the coral. Unfortunately this individual had been through the wars, he arrived with one claw completely missing and the other broken (missing half of the pincer). The poor chap was basically defenceless, goodness knows what he'd been through before he'd been shipped to me. I introduced him carefully next to my largest Acropora but I discovered him hiding under a rock at the base of the clam the following day, he couldn't have been impressed with my choice of coral. Since he had no claws and no coral to live either in I was concerned about how he was going to settle. I gently pipetted a small piece of Mysis toward him and amazingly he managed to manhandle it with his broken claw toward his mouth. After that feeding him was a doddle, he greedily accepted food directly from the pipette. 17 days after introduction he moulted and reappeared with 2 complete claws, not just small claws but a proper pair of normal sized claws. Amazing!
The gorgonian was taller than expected which posed a bit of problem, where was I going to put it? One branch was stripped at the tip, another had flesh missing along its length and it was receding at the base. I had been advised by the shop that it was photosynthetic but as soon as I saw it in person it screamed non-photosynthetic to me. Not that I'm an expert or anything but it's not brown at all which I'd expect to see with a photosynthetic gorgonian. I had ordered it in the hope that it was the purple version of Menella, of which I have seen in photos online but never in person. This did not look like my yellow Menella, the polyps were smaller but it was here now and I would do my best for it. Fortunately it was attached to a reasonable size bit rock (coral skeleton) so I just placed it on the sand whilst I considered where it would go.
Here it is 4 days after introduction.
End on shot showing the whole gorgonian. You can see the stripped branch on the left and the small branch with missing flesh bottom left.
I decided to cut off the stripped top branch but leave the bottom one alone for the time being. After a few days it seemed the gap in lower branch was getting smaller or maybe that was just wishful thinking on my part. I decided to take regular photos to confirm it one way or another. The pictures were snapped at random times during the day and zoomed with my phone so they are not the best quality, oh and the gorgonian was shifted around a bit as I tried to work out where best to locate it in the tank.
This was on day 7 (after introduction).
Day 30 and the gap is now closed.
When I realised the branch above was regrowing I decided to keep an eye on the stripped area at the base too. This was on day 8.
This was day 30.
And this was day 39.
I'm pretty chuffed with that recovery especially since I honestly feared it would waste away in few short weeks. Maybe it is photosynthetic after all, lol.
I let the tank and myself have a breather for a week following 'clamgate'. Clive the clam appears to be fine after the incident and I'm pleased to report that nothing succumbed to an excess of clam ‘protein'. Then I transferred over my two remaining Acropora (gomezi and hyacinthus). I'd been putting off moving these because as we all know SPS can be tricky in new systems but it had to be done and if they didn't make it that'll be that. The A. gomezi was super easy because it's a tiny frag on a frag plug but the A. hyacinthus had grown rather large. I tried my best to frag it off the rock in one complete piece but, yeah that didn't happen. It broke into three, I was going to keep the two largest but in the end I opted to add a single bit only (easier to fix down). Those who followed my old thread may remember that the Reefer 170 had an issue with red bugs. I hadn't seen any of the little red devils for ages but that doesn’t mean that they were all gone, I can only hope. I dipped both frags in Reef Primer and checked them quite thoroughly before they were transferred.
Now we get to the big one. On the 26th April I decided to complete the tank transfer and shut the Reefer down. Prior to this I made one last concerted effort to catch Rei the yellow wrasse and Spike firefish but Rei would only poke his head briefly into the trap and Spike avoided it entirely so it was simply a no go. We did try catching the Spike using nets and acrylic baffles, much chaos ensued with the tiny fish outwitting us every time.
The strip down progressed pretty much as planned with no disasters to speak of, I found it quite stressful nonetheless. We emptied out the water and rocks in stages. The corals that I wanted to keep were cut off and placed in one bucket with the remaining rocks/corals going into another. Spike the firefish was cornered with a net and safely removed. Ming the Pom pom crab was discovered clinging to the underside of a rock. Finally we were left with a tank containing a little water, one last piece of rock and sand. With my breath held, the rock was lifted out revealing Al the pistol shrimp and Flash his Whitecap goby partner hiding underneath. Phew! A careful bit of sand exploration was required to flush out Rei the yellow wrasse. Swipes the porcelain crab was MIA at that point so we had to carefully go back and examine every bit of rock again placing them one by one back into the Reefer as we went. Finally we discovered her hidden in a hole in one of the base rocks. That was pretty much it except for one last thing of note, I discovered a rather scary number of Aiptasia living in the overflow weir along with half a dozen baby sun corals.
Following the transfer Rei the yellow wrasse hid in the sand for a whole 10 days before finally deciding to make an appearance. I honestly thought he’d died from stress or something. Everything else made it through OK which I’m relieved about. The fish were naturally pretty freaked out however so I didn’t take any photos for ages.
The Acros are still alive and growing but have lost colour which is probably down to the poor nutrient situation. There have been a number of reports circulating recently that TMC eco reef rock leaches phosphate and silicates but apart from a brief spike of phosphate during the cycle that hasn’t been my experience at all. Nitrate and phosphate have been consistently registering as zero on my test kits (Salifert and Hanna respectively). In the old days this wouldn’t have bothered me much but the internet has taught me to fear the dreaded D word. For a while I saw a little growth of what looked like some brown algae on the rocks but when viewed along the length of the tank with natural lighting behind was in fact green hair algae. There must have been some nutrients knocking about somewhere to fuel the growth. This algae started to become a little more pronounced so I decided the CUC needed a tiny boost. Two weeks and 6 small Trochus snails later most of this algae was gone, I felt quite pleased with myself. However the removal of the hair algae shifted the balance somehow and combined with a lack of nutrients I began to see the appearance of dinoflagellates on some of my gorgonians. Normally I would take a watch and wait approach but it’s hard not be affected by some of the algae horror stories I have read online. I dusted off the microscope and identified the species as Ostreopsis, fearing a full blown infestation along with the death of my beloved snails I decided action was required in the form of nitrate dosing. I had already been feeding quite heavily to that point including Reef roids and phytoplankton but it didn’t seem to have made any measurable difference. It felt wrong to be actually dosing nitrate! I began with a laughably tiny amount (0.5ml of Brightwell’s NeoNitro per day, 12.6ml will raise my tank volume by 1ppm so 0.5ml was nothing lol). After 6 weeks I gradually increased the dose to 4ml per day, during this time the dino growth increased slightly, mainly evident on the gorgonians, but never turned into the major disaster I feared. The gorgonians still had their polyps extended and the snails seemed fine too. I continued my weekly water change regimen using the opportunity to siphon as much of the dinos as possible every time (not recommended I know but I like to perform water changes).
When the tank was 4 months old I sent off the first ICP sample. I discovered elevated levels of Cobalt and Aluminium. I have no idea where they have come from, leeching from the rock maybe? The nitrate level was 0.02mg/l, phosphate was 0.03mg/l and silicate was 66ug/l. Iodine was a bit low as expected (and some other elements low as per usual).
Finally after 7 weeks of dosing nitrate I started to register 1ppm on the Salifert kit, incredibly the dinos started to recede! This might have been a coincidence of course and nothing at all to do with the nitrate level but either way I am happy.
I am curious to know why I’m not registering a release of phosphate and/or silicate from the TMC eco reef rock. Perhaps the corals are soaking up the nutrients as they are released, the gorgonians are growing very fast. Or maybe the rock is hatching a plan to trip me up later on down the road.
Once the cycle was complete (fingers crossed it was) I switched on the light (I say light because at that time I only had the one unit up and running at that time) to encourage the growth of diatoms. By day 34 the tank looked like this:
I decided it was time to add some clean up crew and a fish. I'd spent a lot of time thinking about what to add as a first fish and I emailed several shops asking about special ordering fish but only one bothered to reply to my query, very disappointing. In the end I decided to go with whatever was available in the shops. We visited two different places and I ended up with 5 black foot Trochus, 5 teeny tiny hermits, a conch and a Sunburst (aka Fathead) Anthias. The anthias settled in a treat and is a really lovely fish. To begin with he hung out at the darker end of the tank (the side without the light) which is pretty much as I expected but after a week or so began exploring the whole tank. The snails and crabs got to work on the algae straight away, I did sadly lose one of the Trochus after 11 days but the rest were fine.
Since the fish and CUC seemed to be doing fine I decided to try transferring over a few tester corals from the Reefer. I decided to move over a couple of the gorgonians first, both have been severely shaded by other corals for a long time and deserved a break plus if they didn't make it I wouldn't be overly upset about it. Anyway as it happened they were totally fine, bulletproof it seems, and are loving basking in some good light again. The Plexaurella was quite bleached (and a bit deformed too) but is looking much happier now. The Muricea is hidden at the back of the tank but is also looking much improved. I know that gorgonians are not everyones cup of tea but I really like how they sway about in the current.
Once it became clear that the gorgonians were not going to keel over and die I decided to press on with a few more transfers especially since the second lighting unit had arrived and been hung. I was also starting to feel a bit of pressure by the rest of the family to just get it done already. I keep having to remind them that slow and steady wins the race. This time I chose to move a couple of more accessible corals, ie the ones not actually welded to the rockwork. The Heliofungia (plus shrimp) and, gulp, the Scolymia. I was particularly nervous about moving the Heliofungia in case Milo, the resident shrimp, decided to jump off and vanish into the rock-work or be eaten by a hungry fish! I needn't have worried Milo was not going to leave his home no matter what, wherever the coral went he was determined to go too, phew!
I wouldn't say that the Helio or Scoly are entirely happy in their new home, they are not as expanded as they were in the old tank. I'm hoping that they are just adjusting to the different lighting and/or the reduced nutrient levels. I hope that they will settle given a bit of time.
I have always had a hankering to try a non-photosynthetic gorgonian, it's crazy I know because feeding them can be so hard but I think they are incredibly beautiful corals. Apparently out of all the species available Menella sp. is reportedly the easiest to keep however in all my years of running a reef tank I have never seen one for sale in a shop. Then amazingly a tiny frag became available online. I reasoned to myself that surely I could find somewhere to squeeze in something that small and before common sense could prevail an order was placed.
The frag arrived looking great and the polyps were fully extended in the pot, I placed it on a frag rack whilst I pondered where on earth I was going to put it. It really is lovely, delicate yellow polyps extending from a dark red central stalk. I have been offering it a variety of dried and frozen foods not really knowing what it prefers to eat or is indeed the correct size for it to swallow. Out of curiosity I decided to film how it would react when I dumped in a load of live Tigriopus copepods in to the tank. I didn't really expect to see much so I was quite surprised to actually catch some action when played back. The footage is not great having been digitally zoomed in on my phone and then cropped on the computer plus the speed has been slowed down but you can actually see pods being caught and more excitingly being ingested! Keep an eye out for the pod that gets caught on the right hand side of the branch and at the time stamp 1.02 you can see the polyp actually swallowing it! Pretty cool stuff I think.
Time will tell if I can manage to keep this beauty alive long term. Now that it's fixed in place I should be able to track any changes be they good or bad.
Last month I was peering into the back of the tank and spotted an odd looking tentacle waving around. I stared a bit closer and discovered a fully grown Aiptasia anemone happily growing back there, argh!! Where did it come from? How long had it been there?? I have absolutely no idea, lol! I could only find the one which in itself appears to be a minor miracle. It was well hidden behind the sun coral from one side and large bushy gorgonian from the other. It was pure luck that I discovered it at all to be honest
Even though it seemed to minding its own business and not harming anything I decided it needed to be dealt with. Out came the Aiptasia RX and I gave it a good dosing. The next day I realised my mistake, the Plexaurella gorgonian that's sited on the rock below looked really rough. All the polyps had retracted and they stayed retracted. Clearly it must have taken an accidental hit from the Aiptasia treatment. For five days it showed no life whatsoever and then on sixth day a 4cm section of the uppermost branch just melted away exposing the stalk underneath. I feared the worst but on day seven some of the polyps on the lower branches started to extend once more and over the next week it gradually returned to normal. Eighteen days post treatment it looked good as new, the entire section of branch that had stripped had been covered over again. Amazing!
Oh and by the way there's no sign of the Aiptasia (for now).
Coral warfare/shading is a becoming more and more of an issue as you would expect for any reef tank approaching 3 years of age. Well perhaps not if the tank had been sensibly/lightly stocked but I guess this hasn't happened. Common sense seems to fly out of the window where myself and reef tanks are concerned.
Most of what I'm going to post is kind of good really. Generally the corals are growing well but there are some that are losing the battle for survival.
The Stylophora needs regular trimming to prevent it from growing up to and touching the left hand glass wall. Its base continues to expand and kills off areas of contact with two neighbouring Montipora as it goes. It has also (along with the Pinnigorgia gorgonian) almost completely shaded out the Beach Bum Montipora. The Beach bum is fading away and there is nothing I can do about it, it's pretty much impossible to relocate. I try not to dwell on this fact too much, it's too painful. Big mistake. Big. HUGE!
I removed most of the green plating Montipora a while ago but it's making a comeback and shading the corals below again. I should never have introduced a frag of this in the first place, I just knew it would end up causing issues in a small tank but it was free and I just couldn't throw it away. On the plus side I must admit it is a lovely vibrant green colour.
The encrusting 'Superman' Montipora is possibly worse than the green plating Monti, I am definitely in need of some marine Kryptonite for this particular coral. At one point it grew up along one side of the clam till the Crocea decided enough was enough and forced its shell open wide enough to snap a good chunk of the the Montipora right off. The Superman Monti also kills any Seriatopora hysterix it touches and has encrusted over nearby Acropora like they were nothing but bare rock. Interestingly it has actually run out of rock space to the rear and has started growing out in a thick plate like formation instead.
I grudgingly accepted the loss of the purple tipped Acro frags to the Superman as they were not thriving anyway (due to the presence of red bugs) but it was harder to take the potential loss of the Acropora gomezi. Despite the parasitic bugs, the A. gomezi still showed nice colouration, not what it should look like under normal conditions but still nice. For months I gritted my teeth and watched this Acro be overgrown, but right at the last minute I decided to frag off the remaining two branch tips. I fixed both of them to the same frag tile and plonked it on the sand. A quick survey with the magnifying glass showed me that the tiny A. gomezi frags are still providing a home/food to the red bugs. I could remove and dip them (repeatedly if needed) but if the bugs are present elsewhere in the system then they will just become reinfested again. The frags have encrusted on to the tile but that's about all they've done at this point. One of the branch tips had a close encounter with the Scolymia thanks to a hermit crab, and got stripped. It's almost recovered bar for a tiny bit of algae covered skeleton at the very end. You can see one red bug highlighted but the arrow in the photo below.
The only other Acropora species remaining in the tank is A. hyacinthus (aka Red Planet), I have yet to discover any red bugs on it but that doesn't mean there aren't any lurking out of sight. Interestingly this Acro has been looking better recently colourwise, it's actually starting to look red once more, well pink at the very least.
The Scolymia continues to look good. It needs to be moved in the not too distant future as the Favia behind is creeping ever closer. I can't afford for those two to meet! Knowing my luck the (much) more expensive coral would be the loser if they clashed.
The Favia has completely overrun the Cyphastrea that used to grow to the right of it and continues to bubble up towards the Acanthastrea to the left. There's been no full on attack as of yet.
The Acanthastrea are surviving but not really thriving. I know that they prefer lower lighting conditions but the plating Montipora above is shading them too much at present. I have been trying to feed them to try and make up for it but 9 times out of 10 Rei the Yellow wrasse steals the food.
The Oxypora keeps expanding ever so slowly, it is also somewhat lacking in light these days.
The Utter Chaos zoanthids are a complete nightmare. They grow so fast and don't seem to be bothered by anything (at least nothing they have encountered in the tank so far). SPS corals are fair game, they just reach up shade out an area of coral until the flesh recedes and then they colonise the dead skeleton. I'm sure that this is a familiar story to many other reef keepers. Having never kept zoas before this is a new one on me. They have grown up the side of the clam and were beginning to reach over and shade the mantle before I decided to scrape them off. A temporary fix as they are encrusting again.
To be fair it's just the Utter Chaos zoanthids that are causing a headache, the rest are much slower growing (aside from growing out onto the sand which is making it hard for Lurch the conch to navigate round the tank).
The Heliofungia has grown to a lovely size but is really squashed up in the front left hand corner of the tank. It remains attached to the small rock and so cannot move around. This is possibly a good thing as I'm sure there would be carnage if it could scoot along the sand and relocate itself. It expanded so much that it was stinging the orange Dendrophyllia to the right of it.
The Lobophyllia has been doing OK, it's really slow growing but since it's tucked away at the side of the tank with not great lighting then that's not exactly surprising. It started off with one head and now almost has three.
Unfortunately one night it suddenly launched an all out attack on the Black sun coral. Before now it had been almost completely overgrown by the Utter Chao zoanthids and not retaliated but clearly the threat posed by the Black sun was a different matter. It stripped three branches of the sun overnight.
Since the orange Dendrophyllia and black sun both needed moving, plus I (still) had the Balanophyllia sitting in the sump I decided space needed to be made for them elsewhere. In the end I pulled out 100+ Utter Chaos zoas, clipped a few branches of A. hyacinthus and removed all of Seriatpora hystrix. The Seri broke into pieces during removal and I decided to keep just a single piece and reposition it a little higher up. This left a space big enough to just about squeeze in the sun corals, now I have quite a nice little cluster of NPS corals on the right hand side of the tank.
After spending over a year and a half in the sump the Balanophyllia is finally back in the DT once more and it's looking good, I don't know why I struggled with it so much. I wonder if perhaps it had some sort of infection that caused the flesh to recede before. It's good to see it back to full health (fingers crossed). I'm also thrilled that the accompanying hitchhiker bivalve is still alive too, I have no idea what that is eating but it must be filtering out enough as it has grown larger since introduction.
The yellow Dendrophyllia remains in place next to the Heliofungia, it has encrusted onto the rock work so I'm not going to mess with it. Eventually I expect it too will be stung but that's a problem for the future. In just over a year this Dendro has increased from 3 to 15 separate heads with another forming. Such a lovely looking coral.
The Pinnigorgia gorgonian goes from strength to strength, it grows so fast and always fully extends its polyps. I have cut off a number of branches of it already and need to trim it some more. The Muricea and Plexaurella gorgonians are much slower growing tucked away at the back of the tank.
That's it for now, I will post an updated full tank shot in a few days' time.
I have lots to update, hmm where to begin? I think I should probably get the bad stuff out of the way first.
Forgive me Father for I have sinned. For quite a while I had noticed that I was harvesting less and less macro algae from the refugium, growth had slowed to almost nothing at all despite there being plenty of nitrate and phosphate available. The days of my tank having low nutrients were certainly in the distant past as they had been slowly but surely creeping up. At the last ICP analysis nitrate was sitting at 11.5mg/l and phosphate at 0.13mg/l. I'd also noted that the mini brittle stars that used to thrive in amongst the algae had dwindled from hundreds to zero (there are still lots in the DT). I'd come to the conclusion that Charlize the hitchhiker crab had been supplementing her diet with some brittle star meat. Anyway hair algae had taken a firm hold in the upper half of the refugium and was choking out the growth of macro algae below. This meant that there was even less algae available to the crustacean residents (Charlize and also Bruce the Emerald crab) at the bottom of the refugium. Then at the beginning of December, I discovered what was left of Bruce, had he also been eaten by Charlize? RIP Bruce.
So on the 16th December 2019 I decided then to take the refugium out for a good clean, removing the old mud substrate and replacing it with some new, a long overdue task I must admit. I carefully salvaged as much of the macro algae as I could (a mix of Caulerpa racemosa and Chaetomorpha) and placed it, along with the naughty Charlize, into a bucket (with tank water obviously). I then disconnected the refugium and set about cleaning it.
Once everything was clean(ish) I added a new layer of mud, refitted the refugium and carefully filled with water. After a while I reintroduced the macro algae and crab. So far so good, however things were about to take an unfortunate downward turn. It seems that by cleaning the refugium and/or replacing the mud I had altered the water chemistry and not in a good way either. The redox value dropped to 250mV and stayed there. Under normal circumstances the redox probe reads somewhere between 350mV to 450mV and to be honest I don't pay that much attention to it. The numbers bounce around depending on whether I've just fed the fish or done a water change. A value of 250mV however was definitely not normal. I wondered if the probe was reading accurately so I cleaned and recalibrated it but still the readings remained low.
A few days after cleaning I noticed some suspicious looking brown algae starting to appear in the refugium and I just knew this wasn't going to be good. Sure enough after about a week or so I started to see signs of it appear in the DT too. It began by coating the gorgonians, the Plexaurella was particularly affected and closed up. Ten days after cleaning I discovered Charlize the hitchhiking crab dead in the refugium. Nooo! I couldn't believe it and felt so terrible guilty. Why did she die? My immediate thought was that the brown algae may have been the cause as some species of dinoflagellates are know to be toxic. I've have not been unfortunate enough to have to deal with this type of algae before but I've certainly read about it a lot. It looked just like typical dinoflagellates, brown and snotty with trapped air bubbles but just to be sure I took a sample and dusted off the microscope.
My suspicions sadly proved correct. The tiny oval protozoans were swimming in a circular motion around an anchor point like a tetherball which is typical of Ostreopsis sp., this is indeed toxic to snails and other herbivorous creatures. I've read many horror stories regarding dinoflagellates in reef tanks, so to say I was feeling depressed was a bit of an understatement, I had visions of all my corals covered with brown snot and the sand littered with shells of dead snails.
According to my research there is no easy way to rid a tank of dinoflagellates and I certainly wasn't keen on the idea of performing a 5-7 day black out. I decided not to panic and continue tank maintenance as normal. I continued with the weekly water changes (yes I know these were not advised) and siphon out as much of the 'snot' as possible in an effort to give the gorgonians a tiny bit of relief. I don't know if it helped them but it certainly made me feel better. In the ensuing days the dinos spread to the tips of the Seriatopora hystrix but surprisingly nothing else seemed affected. Every morning I would count the number of snails to make sure they were all still present and correct.
The redox level remained very low so on the 14th January I sent off a sample of water for ICP analysis just to check if the mud was leeching out something nasty but as you can see from the link below the results looked OK. Nitrates and phosphates were lower than the previous test but not that low.
Since I'd effectively removed most of the beneficial bacteria and critters from the refugium (except for amphipods and mysid shrimps) I decided it might be a good idea to add some diversity back in the form of some live rock rubble. This proved easier said than done as nobody seems to stock actual live rock anymore, it's all artificial or dead rock and bottled bacteria these days. I tried ordering some in from a local shop but when I went to collect it, it was just a bag of dry rock, sigh! In the end I located an online shop that was out of stock but expecting a fresh delivery of Australian live rock in the next few weeks or so. I decided to preorder a small amount and crossed my fingers that it wouldn't take too long.
In the meantime the redox gradually started to creep back up again and by the end of January it had hit 350mV once more, the gorgonians started to pick up again. The first to bounce back was the Muricea followed by the Pinnigorgia and finally after over a month of looking completely dead the Plexaurella shed a layer of algae/mucus and the polyps came back out again, sadly a couple of branches had stripped but at least some of it was still alive. I also only had to frag off one of the Seriatopora branch tips and the rest bounced back in no time at all.
As of today the dinoflagellates have almost completely disappeared from the DT, if you check the Pinnigorgia very closely there is still some evidence of some thin brown strings in one area of low flow but there's not much left at all. I am hoping in another month or so it will have gone altogether, I have my fingers crossed.
Oh and just as things were starting to look up I received acknowledgement that my small order of live rock was available and ready for delivery (20th February 2019). That story will have to wait until another post, oh the stress is never ending....
The Montipora, despite my best efforts to kill these frags, have all survived and are showing signs of growth. :o)
As for Acropora #2, there are no signs of any remaining red bugs (yet!), the remaining piece of encrusted coral looks like it may well survive to fight another day. The polyps are out at least, indestructible or what! I don't know what I will do if the bugs reappear, there are not many options left to me now other than just living with them or trying a pipefish for biological control.
Acropora #3 continues to make a slow recovery from the blistering issue.
The Plexaurella gorgonian has made an amazing recovery since it was moved to a different location. The damaged areas of branches have grown over already and it's pretty much back to its previous fluffy splendour.
I'd like to say that everything is on the up but just as one set of problems looks to be solved another rears its head. I've noticed that the Red Tuxedo zoas have not been expanding as they used to and some actually appear to be shrinking. Nudibranchs I wonder? Sigh, there's always something I find to worry about, lol!
Anyway today I got my camera out and snapped some top down coral shots. I really want to get some new photos of the the fish, especially the wrasse but they are so very camera shy.
Now that I'm down to four Red Spot Cardinals I've noticed that they no longer shoal together. Two of them hang together in the back left-hand corner of the tank, the third swims alone in the back right-hand corner and the fourth, the smallest one, swims right out at the front of the tank. I must admit I do miss seeing them all together.
As for the Nudus gobies I've not got a clue what they are up to any more. They used to be out all day long but now they are mainly hidden underground doing goodness knows what. I wish I had X-ray vision so that I could see what they are doing. They are using the pistol shrimp's burrows; are they interacting with him at all? I would be nice to think that one day they might pair up but I can't see it happening at the moment
Will, the blue-legged hermit crab shed his exoskeleton this week which reminded me that it'd been a while since I added any new shells. As soon as I dropped in some larger accommodation he marched up to the nearest one, whipped his naked bum out of his old shell and moved into the new one. Has he no shame, lol! Here he is showing off his bright white new shell soon to be covered in coralline no doubt.
I noted in my June update that the Plexaurella sp. gorgonian had a damaged area on one of its branches. Well, a couple of days following that two more small damaged areas appeared and this time the gorgonin inside was exposed. The polyps then retracted completely. I waited for a week in the hope that it would miraculously recover but the polyps remained hidden and a layer of algae began to cover the branches. I decided then to take action and move the Plexaurella to a different area of the tank, if I left it where it was it would be a goner in no time at all. Finding a new location proved somewhat tricky as real estate in the tank is limited these days (ahem, what did I say about not over stocking my tank with corals!). In the end I decided to fix it close to where Acro #2 used to reside, it's not really an ideal spot long term, especially if the tiny remaining base of Acro #2 survives and sprouts new branches, but that's a problem for another day. Anyway I doubted that the gorgonian was going to make it but it appears I might be wrong. The following morning the polyps began to extend again and now 3 days later they are almost all back out again, it's not back to its previous fluffy glory but compared to how it looked before moving it's amazing. So was it a flow issue or a lighting issue? Or was the Seriatopora hystrix to blame, it was directly down flow of the Seri, maybe that was releasing some noxious substance that the gorgonian didn't like. Now I need to wait and see if the damaged areas can be recovered.
