Time for a proper tank update starting with the fish.
Sadly Rocket the Red Spotted goby vanished on the 29th December 2019. In the few days prior to his disappearance he hadn't been eating as vigorously as normal, did he die from old age or was there some other reason (perhaps refugium related)? I had him for just over a 18 months. This means I'm down to just one nano goby now in the form of Hop the Nudus goby. Hop was one of the first fish to be added to this tank in December 2016, he was introduced along with a female Nudus goby and a Red Striped goby. His mate passed on after 15 months and the Red Striped goby after 22 months. Hop has been with me for 27 months at this point so I'm worried how long he has left. The clock is ticking, I really wish nano gobies had a longer lifespan. I can't always locate him every day as he spends a lot of time hidden in his sandy burrow but he usually pops out for food whenever he feels like an extra snack. Even when he's not been target fed his belly always looks rounded so he must be finding plenty of pods to munch on when underground.
Edna the Possum wrasse (Wetmorella tanakai) has been with me for just over 2 years and 2 months now. She's quite secretive but much bolder now that the corals are a bit bigger. She flits from rock to rock when the light is at its peak but can be found swimming out in the open when the lights are dimmer. She loves PE mysis above all other frozen food and will home in on the bigger pieces even if they do take several 'chews' before she is able to swallow them.
Kylie the Pink Streaked wrasse (Pseudocheilinops ataenia) was added next so she has been a resident for 2 years and 1 month. Another model reef tank inhabitant, slightly more active than Edna, loves to hunt for 'pods'. Her favourite food is fish eggs which she will take straight from a pipette. I wish I could find her (him?) a mate but whenever I see another Pink Streaked wrasse in a shop I wimp out in case it's the wrong sex.
Rei the Yellow wrasse (Halichoeres chrysus) has been with me for a year and a half and has grown enormously. I still think of her as female but she has transitioned into a male now. If I'm totally honest this fish is too big for the tank and really needs to be moved on. I'm just not sure if he could be caught that easily, sometimes I just have to sneeze near the tank and he vanishes with a puff of sand.
Tinker and Belle the Pintail wrasse pair have been with me for 16 months and they are still going strong. I did fear that I might be asking for trouble introducing two of these fish as females of this family have a reputation for changing into male in captivity and this almost always results in all out war with another male. So far, I am relieved to say this has not happened. Will it happen in the future? I do not know. Tinker regularly displays to Belle and occasionally chases her around the tank when he's feeling moody, most of the time however they co-exist quite peacefully together. These fish love to eat and will try to consume as much of the food as they possibly can before the rest of the fish can reach it.
Jessie, the Rainford goby is the most recent introduction, I've had him for just over 6 months now and he is the most enchanting fish, totally peaceful and not at all shy. He naturally gives way to the larger wrasse when they come barreling past or at feeding time but he is always waiting at the top of the tank (along with the male Pintail wrasse) to try and grab as much food as he can. He can often be found sifting sand, pecking copepods off the back wall and to a lesser degree, eating hair algae.
That's the lot, every now and again I toy with the idea of adding one more fish but I am hesitant to upset the status quo. All of the fish get along and are healthy so I should be content with that, right?!
My next update will be corals.
Apologies for the delay in updating this blog. I'm pleased to report that Tinker the male Pintail wrasse DID survive his cave diving experience after all. He refused to eat for three whole days following the ordeal but then on the fourth day he tried sampling a couple of small pieces of Mysis and then on subsequent days he ate a little bit more at every feed. He was feeding pretty much normally again after two weeks. His wounds (lost scales and shredded fins) repaired themselves in short order once he began eating again. I hope he's learnt his lesson not to go wedging himself into small holes in the rock again.
Jessie the Rainford's goby continues to do well. He is such a sweet little fish, keeping to himself whilst going about his daily business hunting for pods and sand 'chewing'. I think he's grown a bit since introduction.
On the 18th December, Edna the Possum wrasse will celebrate her second birthday in the tank. She is visible much more than she used to be, the corals have grown in and she can weave her way through, under and around them without exposing herself to the scary open water too much. This doesn't apply at feeding time when she's out ready and waiting to sneak a choice piece of her favourite food, PE mysis.
Hop the Nudus goby celebrated his second birthday on the 3rd December, he may have lost his mate back in March but he is still going strong along with Al, his shrimp partner. Red Spotted pistol shrimps are reported to only pair with Whitecap gobies but after mine sadly jumped out (through the mesh of the tank lid) the remaining shrimp accepted the Nudus pair instead. They have been together for well over a year now.
Before I sign off for today I'll leave an updated shot of the two Dendrophyllia sp. because why not! They are just so pretty. Notice the Pintail wrasse sleeping under the rock.
I hope to update more fully in the next couple of weeks. I have just one new coral addition to report.
The tank has survived to reach its second anniversary today, how the time has flown. Needless to say after two years of running, the exciting stocking phase is pretty much over with (although never say never, lol!) and I've moved on to the not quite so exciting fragging phase.
The first coral that needed a proper pruning was the Seriatopora hystrix. It has grown in rather an unruly manner and some of the branches were growing over the top of the clam (a definite no-no!) and a good section was also now obscuring my view of the sun coral, making it harder to feed. The tips are easy to frag but I found that when trying to cut branches further down, whole sections would break off instead, so I removed far more of the coral than I intended. Oh well it will recover given time (assuming that the Utter Chaos zoanthids don't take it over completely).
Finally, I am able to see the sun coral in all its glory again. As you can see it does try to keep the branches of the Seri in check by stinging and killing off the tips that stray too close. If you look closely you can also see a few of the baby sun polyps that have settled on to the rockwork to the left. The whole tank is pretty much spotted with baby suns right now, even the Scolymia already has one settled on its skeleton.
Talking of sun corals, the Dendrophyllia frag I added in August is doing really well, it started out as 3 heads and now has 5, with another 4 more developing. This seems like a much faster growth rate than the Tubastrea, or maybe it is just more noticeable due to its branching formation.
I have also been lucky enough to pick up another Dendrophyllia frag from a fellow reefer. Morphologically it looks the same as the yellow one so it's possibly just a different colour morph (or perhaps it's a different species, I don't know). I so looove these corals, I know that they are only at their best after the lights go out but I simply don't care, I think they are spectacular! I sometimes wonder if I should have just gone with an NPS tank and be done with everything else, lol! Ideally I'd prefer to feed these corals during the day so that I can admire their beauty with the lights on but it's so darn frustrating. The wrasse try to steal the food and 98% of the time they are successfuI before the polyp has a chance to fully ingest it. No matter how I defend the coral, the bloomin fish sneak in and grab it most of the time. It's just not worth the effort and stress it causes (to me and the coral). Oh to be outwitted by a few fish....
Anyway back to fragging. The second coral that needed reducing in size was the green plating Montipora, I'd been psyching myself up to do this for months. I knew the time had finally come when the Acanthastrea corals growing directly below it started showing signs of struggling, they were at that point pretty much completely shaded out by the coral above. I kept putting it off because the Montipora had grown into such a perfect saucer shape and looked lovely, I knew that once I'd had at it the shape would be ruined. Unfortunately I didn't take any photos of either this or the Seri before I began chopping, I don't know what was I thinking? Anyway the plate coral may look quite delicate but it was surprisingly hard to frag, lower down the skeleton is deceptively thick. I took off a good couple of inches around the edges on the right-hand side and probably should have done more but that's a problem for another day.
Now that the there's a bit more light, the Acanthastrea 'Lava Glow' looks good again. Its smaller brother to the left of it is unfortunately still somewhat shaded. However this coral has never really grown well even when it received better lighting. I did try to move it to another location recently but it's fused to the rockwork so I'm afraid it's there to stay.
The third coral that needed to be fragged was Acropora hyacinthus. I've been nipping the front tips off here and there for a while as they grew towards the front glass but more drastic action was needed this time as I was no longer possible to clean the glass in front of it. Due to the fused branch growth it was now impossible to remove individual bits so the best remedy for the long term was to remove the entire front half of the coral and as with the Seriatopora more was removed than intended. In fact there's not much of the coral left now, just the base and one main branch. Hey ho!
Whilst fragging the A. hyacinthus a large chunk snapped off at the base and fell right on top of the Scolymia. Argh! The Scoly looked very unhappy for a few days and remained shrivelled up, naturally I feared for the worst but fortunately the reefing gods were smiling down and it has bounced back to full glory once more. To say I'd have been upset if a frag that originally cost £15 took out a much, MUCH more expensive coral would have been a bit of an understatement to say the least, lol!
The Scoly loves to eat but never shows its tentacles till after the lights go out so I only feed it at that time. I offer it krill or LPS pellets once or twice per week.
The Favia has grown from a frag the size of inch squared into quite a big beastie and has spread out not only over the rockwork but also out onto the sand towards the Acanthastrea to the left of it. There used to be a good gap between the left and right rock piles, a space in which the conch could easily pass through but now his shell won't fit through at all. I fear that it's only a question of time until the two corals start fighting each other and there won't be much I can do about it as they are both well and truly encrusted on to the rockwork, It won't be pretty I'm sure!
The Heliofungia also continues to do well, there's no sign of it wanting to break away and wander round the sand (which is fine by me!) nor are it's offspring. As you can see from the photo below the coralline algae growing on the glass is a bit of a pain. I want to scrape it all off but I don't want to damage the coral during the process. Everywhere I've read says if the flesh gets torn then it's "hasta la vista baby!", so I feel it's best to just leave it be.
Jessie the Rainford's goby has settled in beautifully and whilst he always gives way to the much larger wrasse at feeding time, he's not shy at all. He roams all over the tank, pecking at algae and chewing the 'sand'. He now feeds really well on frozen food and tries his level best to grab as much as he can before the greedy wrasse hoover it all up, I still offer him a bit extra via a pipette to make sure he gets enough to keep his little belly full.
Sadly I haven't seen Candy the Red Striped goby (Trima cana) since the 8th October. He/she was one of the first fish added to the tank on the 3rd December 2016. I understand that nano gobies do not have long lifespans, only a couple of years, so I'm assuming it was just his time. Two years is just too short sadly. I can't help but wonder how long Hop the Nudus goby will be around for now. He was also added at the same time as Candy and he already lost his mate earlier this year (March).
Sadly I don't have a recent(ish) photo of Candy to share as once the zoanthids grew over his rock he took to hanging out behind Lobophyllia where he was difficult to photograph. I'll post this sneaky shot taken last year instead. :'(
The rest of the fish are fine.
I have a new invert (see, I can still squeeze more stuff in lol!), a crinoid squat lobster. I tried keeping one of these adorable little crustaceans back in 2016, when the tank was relatively new. Sadly it vanished after just 20 days and I vowed not try another... then I came across this little guy. I reasoned that now that the tank is mature this itty bitty crustacean would stand a better chance at survival so he now resides in my tank. As I type this, it's been 27 days since introduction and I'm happy to say that he's taken up permanent residence amongst the branches of Seriatopora, hiding underneath the relative safely of the Utter Chaos zoanthids during the day, he blends in extremely well with the orange of the polyps. He's been named Jaffa and readily accepts all sorts of food from the pipette, I am hopeful he will do better than Stripes did.
Jobs I still need to do. I need to frag the branches of the Stylophora that are growing too close to the glass on the left-hand side and try and remove some of the many Utter Chaos zoanthids that have spread round the tank (I really regret adding those devils).
I've run out of time now so I'll sign off with the obligatory full tank shot.
To this, in two years.
A few weeks ago I decided to take action against the hair algae growing on the skeletons of my recently deceased Acros. I armed myself with a toothbrush and tried scrubbing the affected areas, at the same time I performed a water change enabling me to siphon out the algae as soon it was liberated. It didn't take long for me to realise that this just wasn't going to work very well. It was almost impossible to reach some of the areas without running the risk of damaging the surrounding corals and even in the areas I could reach I was unable clear it all off. Worst of all during the process, thanks to my clumsiness, I snapped off the branch tips of several corals. So no more scrubbing for me!
Instead I decided to embrace the hair algae rather than hate it. For years I've wanted to try keeping a Rainford's goby (aka Court Jester goby, Koumansetta rainfordi) but never had the courage to try one because of their reputed difficulty in accepting prepared foods plus need for filamentous algae in their diet. As luck would have it I came across one of these little fish during a visit to a local fish shop, I observed it for a while whilst running through my Rainford's goby purchasing check list.
1. A healthy looking specimen (sleek looking without a concave tummy). ✓
2. Eating prepared foods (I watched it tuck into frozen mysis). ✓
3. Mature aquarium to introduce it to (the tank is 22+ months old now). ✓
4. Filamentous algae present on which it can browse (yes indeed!). ✓
5. No super aggressive tank mates such as dottybacks or hawkfishes to harass it. ✓
My biggest concern, apart from the feeding issue, was the presence of my Yellow and Pintail wrasse, they are much bigger fish and I had no idea how they would react to the introduction of a small and delicate goby. I was fairly confident that the other nano gobies and wrasse would have no issue. After much umming and aahing I decided to take the risk and bring the little fish home with me.
Amazingly, once introduced the new goby was completely ignored by all the resident fish, I was certainly not expecting that! Despite the lack of aggression the goby was far from relaxed which I suppose is normal for any new fish and the Yellow/Pintail wrasses are undoubtedly quite scary to a timid little goby. He didn't hide but kept low down on the sand in the front left-hand corner of the tank and actually looked to be struggling with the brisk flow so I turned down the powerheads to give him some relief. That night he created a cosy little depression in the sand underneath the Utter Chaos zoanthids to sleep in. By the way I have no idea if this fish is male or female, I decided to go with male (a tough little guy with any luck) and named him Jessie.
Over the next couple of days Jessie slowly settled in and started exploring the tank. I can confirm that he does peck at/sift the sand and eat hair algae, result! I can't see him being voracious enough to eradicate the hair algae or even keep it in check for that matter but that doesn't bother me right now, I'm just thrilled that he's eating. He was still nervous of the bigger fish and would dart out of their way whenever they approached and when it came to frozen food he would look interested but was not confident enough to grab a bite. Fish have to be quick off the block in this tank when it comes to food as the greedy wrasse tend to hoover it up in no time at all.
I increased the number of feedings from three to four times per day and on the fifth day post introduction, Jessie felt confident enough to sneak a couple of small pieces of Gamma Mysis. By the eight day he was up for trying to tackle a large piece of PE Mysis but this was a bit beyond his capability, he tried 'chewing' it 4 times but as he spat it out for yet another attempt a wrasse swooped down and stole it, lol! To ensure that he is getting his fair share I have introduced him to the magical food dispenser (me and a pipette). I like to spot feed most of my livestock (fish, corals, shrimp and crabs) and naturally the fish know that the pipette means food so it takes a bit of time and patience to get the food to the intended target. The Yellow and Pintail wrasse try to steal as much of it as possible, I swear given the chance those fish would keep eating until they popped! I have to wait until these fish 'appear' to lose interest before quickly releasing a piece of food in front of the intended recipient. Fortunately, Jessie is a quick learner and took to the pipette trick remarkably fast, he's even started pecking at the tip in his impatience for the food to appear.
It's early days for this fish but so far I think it's looking promising. I will certainly keeping a very close eye on the state of his tummy to make sure it stays full looking and not sucked in.
A quick video clip taken today of a rare sighting of the two Tomiyamichthys nudus gobies together with the Red Spotted pistol shrimp (Alpheus rubromaculatus). Sorry the footage is a bit shaky but it was a spur of the moment kind of thing. If I'd have waited to set up my phone on the the tripod I'd have missed them entirely. These guys are too cool!
My tank is exactly a year old today! Wow, where has the time flown to? I've been a bit lax with the updates recently so there's lots to catch up on.
First lets get the bad news out of the way. I'm afraid that I've lost the lovely Tridacna maxima clam, it simply never thrived in my tank. Before adding it I carefully checked the shell looking for any nasty hitchhikers but I never found any. I must have missed some (or their eggs at least) as I started to notice some pyramid snails feeding on my precious Trochus and Turbo snails. Nooo! I checked the clam regularly at night with a flash light but never found any of the little devils feasting on it. After two and a half months it finally it became clear that the clam was doomed so I decided to remove it before pollution became an issue. I checked it over again when it was out of the tank and still couldn't find any pyramid snails on it. These guys are so small and clearly hide really well! Later on three teeny tiny ones did emerge from inside of the clam, it's hard to imagine that just three could have any impact on an animal so much larger than they but clearly over time they do. Unless of course the maxima was suffering from something else too?
At this point there's not much I can do about the pyramid snails, I am removing any that I see every day and I've become quite adept at spotting them now. On average I remove about 10 per day. The wrasse are sadly not eating them, come on guys I could really do with a helping hand here, sheesh earn your keep why don't you!! At least I haven't lost any of the snails yet and my original Tridacna crocea clam seems to be doing fine, it's laying down new shell so I take that to be a good sign for now.
The other blip on my reefing horizon is the Balanophyllia. It just doesn't look as good as it once did and I can't work out why. Am I feeding it too much or not feeding it enough? I had been offering it a piece of food once per day (at night), generally PE mysis, clam, Krill or lancefish, perhaps that wasn't enough to sustain it? So I decided to up the feedings to multiple times per day (anywhere between three up to a maximum of five a day) but this seemed to make no difference at all (in fact the coral looked a little worse) so now I'm trying less food. It's really frustrating because the sun coral is looking fantastic on a single feed per day.
Apart from the above everything else seems to be doing OK. The fish are all good, Rei the Yellow wrasse eats like a horse and is noticeably bigger. The best news is that my Tomiyamichthys nudus gobies have finally paired up with the Red Spotted pistol shrimp so I get to see them all much more now. The male goby still goes MIA every now and again but always resurfaces at some point. The gobies and pistol shrimp do not naturally associate together in the wild but I suspect they have done so in my tank because there are simply no other alternatives.
The corals are getting bigger and some are starting to get close to each other already, war is on the horizon I expect.
The zoanthids are spreading nicely especially the Utter Chaos, these are reproducing at a phenomenal rate and unfortunately over taking some of the original slower growing morphs. Whatever was afflicting the Red Tuxedo zoanthids seems to have subsided and I've not lost any more recently, I hope that's the end of that.
After a bit of a slow start the algae in the refugium has really got going now and the amount of life in there is incredible. It's amphipod, mysis shrimp and brittlestar heaven! Charlie the hitchhiking crab is alive and kicking and still growing. She was such a tiny thing when I first noticed her in the DT hanging out in the Seriatopora, now she's huge in comparison.
Life in the refugium.
Whenever I harvest any algae, I spend the following 30 minutes rescuing brittlestars from amongst the fronds. Well I can't just throw them out can I? It's easy to see how they are reproducing by division.
My first canister of ATI Carbo EX came to the end of its life in September, it lasted just over 3 months which I don't think is too bad. I have decided to continue with the CO2 scrubbing and have replaced it with a fresh cartridge.
Last week to celebrate the fact that the tank was approaching its first birthday I decided that some new additions were required. There was a gap (left by the T. maxima clam) that was just crying out to be filled. OK it didn't really need to be filled but what can I say, any excuse to shop for new corals.
I decided another encrusting Montipora sp. would do nicely and since it was likely to be the last addition (never say never tho) I wanted something special. I decided the Beach Bum (what a name!!) Montipora would contrast nicely with the three that I currently have. Since I was mail ordering from a fellow reefer I found I couldn't just buy the one coral so I ended up with frags of Hawkins Echinata (Acropora echinata) and a Sunrise Goniopora too. My name is Lisa and I'm a coral addict, lol!
Here they are on the sand awaiting fixing (squeezing!) in place.
Phew that was a marathon (are you still with me?) before I sign off I'll add a few more updated photos. After all who doesn't love a bit of eye candy?!
Some bad news to report.
First up, the King Midas zoanthids I introduced just under 4 weeks ago. For the first week I left them sitting on the sand and they looked great, opening up nicely so I decided to fix them down on the rear of the right-hand rock pile. Oddly after that they refused to open up again. Hmm, I thought maybe they don't like that spot so I removed the frag plug from the rock and sat it back down on the sand at the front of the tank again. Happily they started to extend once more so a couple of days later I fixed them to a new spot not that far from where they were sitting on the sand. Sadly they never opened up again and started to shrink. As it stands they are pretty much all gone now, a couple of tiny polyps remain but they are closed up tight and will no doubt soon fade away. I am at a loss as to why these particular zoanthids have not survived when my other 7 varieties appear to be doing well. It's very frustrating and I'm quite sad about it because they will be my first coral loss since I started up. I didn't even manage to take a picture of them when they were open to post here for posterity's sake.
The next loss is not so much of a mystery which makes it all the more maddening although I've only just put two and two together after the damage was done. The two new Red Spotted gobies (Trimma rubromaculatus) are indeed a male and female pair as I've noticed them "gettin' jiggy wit' it" on a number of occasions now. This is a lovely thing but unfortunately means that they don't want any fish swimming near their patch and sadly their patch appears to be the entire rear lower half of the tank. Now this just happens to be the same area that the Red Spot Cardinals (Apogon parvulus) like to hang out. I'd noticed recently that the Cardinals had taken to swimming at the top of the tank where the flow is quite brisk, This a bit odd for them and should have paid more attention to it. It all became clearer this morning as I watched one of them stray just a bit too low and was immediately and aggressively chased upwards by the larger of the two gobies (named Rocket which seems quite appropriate considering the response I witnessed). I'm sure you can guess where this story is going now, skip back to yesterday and one of the Cardinals sadly jumped out of the tank. I was working opposite at the time but did not realise what had happened until it was too late. I feel sure after what I observed this morning that it was being chased by one of the gobies, after all these fish hadn't shown any inclination to want to jump before the Red Spotted gobies were introduced. Sigh, another hard lesson learned, mixing different fish even really tiny ones in a small space is not an easy thing to do.
I have some new stuff. :o)
After searching for ages I located a shop that had some Red Spotted gobies, Trimma rubromaculatus, in stock (finally Facebook is useful for something). They only had two left when I visited but apparently they were a mated pair so I just couldn't leave without them. They've been with me for 4 days now and seem to have settled in a treat. On introduction they were ignored by the other fishy residents with the exception of Candy, the Trimma cana goby. Candy is actually a male Red Striped goby and he was not best pleased to see a another male goby, even of a different species, invading his patch. There was much posturing between himself and what I would assume to be the male Red Spotted goby. No damage was done fortunately and now they appear to be keeping their distance from each other. The new gobies, named Rocket and Sparks, are much more active than Candy and are out and about a lot more especially at feeding times when the nanostream pumps are off. They do find it hard work to battle the flow when the pumps are on and are generally found suctioned onto the underside of rocks or resting on the back wall instead of swimming up in the water column.
In addition to the gobies I also purchased another small frag of zoanthids, this variety is called "King Midas" and comes with some hitchhiking fan worms too, a nice bonus in my opinion. I think I'm pretty much out of space now where zoanthids are concerned. Picture to follow in my upcoming 1st July update.
I also added to my crustacean collection in the form of a Pom Pom crab just because I think these guys are just the coolest. They have such beautiful markings and the little anemones they hold are neat. I hope he (or she) doesn't do too much damage waving them around the tank, lol! No photo as of yet because he's kind of shy at the moment.
In other news Lurch the conch finally got up after his extended snooze. He spent almost 2 whole months hidden under the sand with no movement at all except for the odd glimpse of an eyeball and his proboscis poking out of the sand for an occasional bedtime snack. I'm surprised that he can survive for that long with such little food to sustain him. Luckily he seems none the worse for his 'hibernation' period thank goodness, I just wish I knew what caused it, is it a natural part of his lifecycle or was there some water quality issue that he didn't particularly like?
The Nudus gobies have not been in much evidence since Gordon the Whitecap goby made his leap of faith last month. I used to see them all the time but after the upheaval with the pistol shrimp and the loss of Gordon they hardly ever came out of the burrow system and never both at the same time. Then Hop (the male) vanished entirely, the last sighting of him was on the 18th June and after that nothing. He has been known to go missing before, when guarding eggs, but I generally get to see his head pop out of the burrow every now and again. I was beginning to think that he'd had an altercation with the pistol shrimp and lost or been buried alive under the rocks, eek! Happily no, after 8 days he's back out again like nothing was ever wrong so I guess he had been guarding eggs again after all. I wish they'd let me know so that I don't worry so much, lol!
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.
It's only taken me 4 months but I have finally managed to snap a shot of Gordon the Whitecap goby. It's not much of a shot but believe me it's waaaayyy better than anything else I've managed to take to date. At least he is recognisable as a fish and not just a white blob that could easily be mistaken for a grain of sand, lol!
He's a lot bolder these days and I generally get to see him and Al, his pistol shrimp buddy every day. They are most active towards the end of the day when the lights are going down but I do see Al (or more accurately Al's antennae and claws) at every feeding time. I don't really know what Gordon is eating, I occasionally see him take cyclops/Calanus and even a small pieces of Mysis if Al doesn't get to them first. I also see him strike at 'stuff' unearthed by the shrimp's digging activities so he must be finding tiny crustaceans to eat as well. Most of the time when when the rest of the fish are fed he's nowhere to be seen.
Now I just need to get a decent shot of Al too, this was the one and only shot from tonight's session. I'm embarrassed to post it, but hey you can tell there's a fish and a pistol shrimp in the shot right? :o)
