First the not so good news, I think it's time to hold my hands up and admit defeat when it comes to growing Acropora in this tank. As soon I discovered the first red bug I feared the worst and that certainly appears to have been the case. I had hoped that the corals would be able to survive the parasitisation and for a while they did, growth was slow but steady and colouration looked OK but that's certainly not the case now.
To recap, patient zero (the frag that initially infected the tank) was removed leaving a small amount of encrusted base in the tank, it looked like was going to recover and regrow but progress was so slow that the neighbouring Montipora (Superman) completely overgrew it. The second casualty was the Purple-tipped Acro, this suffered from STN (slow tissue necrosis) and had to be fragged. The remaining frags encrusted onto the rockwork but again showed little upward growth and were in time also overgrown by the Superman Montipora. A tiny bit of encrusted base still remains but I fully expect it to fade away or be overgrown eventually. The A. loripes suffered from RTN (rapid tissue necrosis) whilst I was on holiday and the Red Dragon joined it shortly after. The A. echinata frag also suffered from STN and was fragged but the stress of it being chopped up caused the remaining branch to strip overnight. So this leaves me with Acro #1 which has browned out and is soon going be completely overshadowed by the green plating Montipora (I never actually wanted any plating Montipora in this tank but this was a freebie coral that came in along with an order of encrusting forms and I, like an idiot, assumed it was encrusting one too, duh!). I also still have Acro #3 which is struggling for space next to the large gorgonian and A. gomezi. At first glance the A. gomezi looks OK but is actually covered with red bugs and has put in no upwards growth since its introduction almost 18 months ago!! There is one Acro however which appears unaffected by the Red bugs and that is the A. hyacinthus (aka Red Planet), this has grown relatively well and in fact has to be fragged because it keeps growing too close to the front glass. I cannot find any trace of red bugs on this coral. So there you go, it's no more Acropora for me, perhaps I'll be able to restock one day when the remaining Acros have gone and the red bugs have died out without a coral on which to host.
In case there was something going on with the water quality that I wasn't aware of, I did send off for an ICP analysis but nothing stood out as being particularly troublesome. Strontium, Barium and Manganese were on the low side. Nitrate and phosphate were 3.02mg/l and 0.09mg/l respectively which is the highest they have been but not excessively high, I think (maybe someone may correct me?). Still, I have decided to run a little Rowaphos to bring the phosphate level down a touch. Full results can be seen via the link below.
Now for the better news the rest of the livestock for the most part appears to be doing fine. The Stylophora, Montipora and Seriatopora are all growing great (a bit too great actually). The lovely beach bum Montipora is thankfully still with me and finally showing signs of growth too. Unfortunately it's becoming harder and harder to see with the ever increasing Stylophora situated to the left of it and monster green plating Montipora to the front. Very poor planning on my part! I can just about catch a glimpse of it from the top but I suspect that won't last long. I would really love to move it to somewhere viewable but I doubt that I could get it off the rock even if I had somewhere to move it to which I certainly don't.
The Superman Montipora has completely filled in the space I gave it and is also growing up the side of the Crocea clam shell. I'm not sure if I should be worried about this development or not. I hope it doesn't impede the opening and closing of the clam.
I had to remove the original frag of the Cyphastrea as the Favia next door was remorselessly attacking it every night and anyway I never liked the look of the horrible frag plug. Since its removal the remaining encrusted part has been doing much better, it's still very close to the Favia but seems to have fallen under the radar for the time being. As for the Lobophyllia I had always been led to believe that they are super aggressive corals but the Utter Chaos zoanthids are creeping ever closer without any form of retaliation at all. I had rather hoped that it would keep them in their place.
Sadly the Sunrise Goniopora frag is not doing very well at all. To begin with, it looked great and was encrusting on to the rock it was placed but then it started to lose colour and not extend as much. I tried moving it to the back of the tank where it was less bright but that didn't seem to make a difference. I can only assume that it hasn't been finding enough food, I do target feed it Reef Roids and Goniopower but generally not more than once a week. I am ever conscious of the size of the tank and nutrient levels.
Here are a few recent photos:
Now on to the new stuff!
With the loss of a few of the SPS corals I was needing a pick me up and a new coral (or two as it happens) does the job. For ages I had fancied adding a short tentacled Fungia to the tank and since we had a trip to London planned a couple of weeks ago, a visit to Advanced Aquarium Consultancy was in order. I couldn't believe my luck when I found out the night before that they were having a sale on some of their corals. I thought "fantastic", I can save some money for a change, lol! However instead of saving money I spent more as I ended up buying a Scolymia instead of a Fungia. Oops! It's funny how that happens when shopping for corals. Needless to say I could have spent more, waaayy more, thank goodness I live too far away for AAC to be my LFS.
Apparently it's a Reverse Bleeding Apple Scoly (more red colouration than green) and here it is after 4 days. I've been watching it like a hawk, worrying about its health because frankly it's the most I've ever paid for a coral even with 20% off. Oh but it's so pretty.
I had to remove 4 Asterina sp. starfish from the base of the coral after acclimation, I felt bad about killing them but really, I have enough pest issues to deal with as it is. It's a shame because close up they are quite nice to look at and I love starfish but I can't take the chance that they may become a nuisance. Although it would be cool to have a Harlequin shrimp...
Here is the Scoly in night feeding mode.
Just after the addition of the Scolymia I discovered an online seller was offering frags of Dendrophyllia sp. Now I really love sun corals (well, non-photosynthetic corals in general) and my current Tubastrea is doing great so I convinced myself that I could squeeze in an itty bitty frag of a Dendro too. The coral was listed as yellow/red in colour with the polyps opening up in the day time as well as the night. However as you can see the coral is a uniform lemon yellow in colour with not a hint of red at all (unlike the one shown on the website). No matter though it looks healthy and really rather lovely, it opened up much faster than I expected and is taking in food already which is excellent. I can confirm in my vast experience of one week that it does indeed stay open during the day. I'm not convinced that it's a Dendrophyllia sp. however, it could alternatively be a branching Tubastrea sp. Only an examination of the skeleton will determine that for sure and since I'd really rather it didn't die I'll be content without a positive ID.
Here's a full tank shot to end this update.
I went away this weekend and managed to find the time to visit a few not so local fish shops (as the reef-obsessed tend to do given the opportunity). In the 3rd shop I struck gold and located the Porcelain crab (Petrolisthes galathinus) I've been searching for since I first set the tank up. She is one of the hitchhiking species that are sometimes found in live rock. I used to have one of these peaceful filter feeding crabs in my old tank and knew I wanted one for this tank too. When I arrived back home everything in the tank seemed fine and my crab (a female according to the shape of her abdomen) was duly acclimated and introduced just before the lights went out.
This morning I eagerly rushed down to check on my new crab only to discover that the curse of the Red Spot Cardinalfish had struck again. Another one of them had died, this time I discovered the body, the Lobophyllia was trying its best to eat it! The meal turned to be too much for the small coral to stomach and I was able to remove the dead fish using a pair of tongs. It was at this time that I happened to notice a small shape lying on the carpet to the side of the tank. Closer inspection showed it to be Gordon my Whitecap goby, nooooooo! He had jumped out of the tank at sometime during the night. I do have a mesh lid on the top to prevent any jumpers but somehow he still managed to find a way out, he was a very small fish after all. There is no doubt in my mind that he jumped as a direct result of the persecution by the Nudus gobies. The female in particular went out of her way to terrorise him at every opportunity. I have no idea what will happen to Al the pistol shrimp now and I dare not introduce another Whitecap as the same thing could happen all over again. He's going to have to make do on his own from now on and I expect I won't see him nearly as much as when Gordon acted as lookout for him. I feel so very, very sad today.
On the 18th April I relocated Charlie (or is it Charlize?) the hitchhiking crab from the DT to the refugium. After almost 4 weeks of no-show, today I discovered him (her?) alive and well in the jungle. I am chuffed, what a survivor!
Also I've also been playing around with a new macro lens, starting with some of the easier corals to capture.
A better FTS (with less blurry fish hopefully) and some top-down photos of corals that I forgot to include in yesterday's update.
This tank is approaching the 6 month mark (on the 16th April). Wow, where has the time gone to? It's now well and truly in the 'spotty phase', the back glass is covered with spots of coralline algae and spirobid worms. I have scraped it once already and am now in two minds if I should do it again. Does it look natural or does it just make the tank look messy? I can't decide, answers on a postcard please. :o)
I've had to move the Lobophyllia yet again. The Lobo was very happy in its last spot but, darn it, the snails (Mr Conch I'm looking at you particularly!) just kept knocking it over no matter how hard I pushed it in to the sand. So now I've glued the base of the skeleton to the rock work on the right-hand side at the back. It's not great for viewing but at least it won't get damaged there. Fingers crossed that's the last time I have to move it!
Acropora sp. #2 still appears to be red bug free and the PE looks good. Acropora sp. #3 is on the mend I think, to my eye there appear to be less blistering now. It's not completely out of the woods yet but I'm feeling a little more confident about its future. General coral colouration is not great but I'm not too concerned about that at this point.
My mysterious hitchhiking crab has thankfully moved away from the S. hystrix and has set up home in the uppermost right hand rock. I still don't have a decent picture of him to show I'm afraid, he moves like lightning whenever I get close. So far he's not attacked or eaten anything that he shouldn't, I regularly observe him scraping at the rock work with his spoon shaped claws and he does a great job of keeping that area clean of algae and detritus. He has grown considerably and I am probably not helping matters by occasionally feeding him directly. I have tentatively identified him as Chlorodiella nigra which is a member of the Xanthidae crab family. According to my research they are generally fine when smaller but can become troublesome as they grow and their appetite increases. I am investigating removal options just in case.....
Yesterday afternoon I introduced probably my last fishy additions for this tank, they are still settling in at the moment, pictures to follow hopefully later on in the week.
For the most part the tank is doing OK. There is very little in the way of nuisance algae, the furry stuff that was coating the rocks seems to be fading away without any intervention on my part. The zoanthids are opening up nicely and looking good, so I think the nudibranch problem is solved. The LPS expand nicely during the day and are always ready to eat whenever they sense food in the tank.
Most of the SPS corals are doing well, showing good growth or at the very least basing out. Colouration however is not great for some of them, I'm hoping that with time and stability the colours will improve. Maybe it's a nutrient issue?
There is one Acropora sp. (#3) that does not look good. I have noticed recently that there appears to be blistering to the flesh. This is a new one on me so I did a bit of searching on the web and others have reported this ailment. Unfortunately no one really knows what causes it. Some say that it's due to an imbalance with the big three, i.e. KH, Ca and Mg but in my case I have those parameters well within recommended levels and they haven't fluctuated much either. The only suspect I can think of at this stage is KZ Sponge Power, I began dosing this on the 11th February (1 drop every other day). It may have nothing to do with the problem but I think I'm going to stop using it for a while and see if the Acro improves.
I nuked the tiny Aiptasia that sneaked into the tank on the clam shell with Aiptasia-X and didn't feel bad about it at all. Now I just have to be vigilant for more Pyramid snails. My list of hitchhikers found in this tank is growing ever longer.
I'm happy to report that the fish are all doing fine. It's been just over a month since I added the Pink Streaked wrasse and I'm thinking that the time might be right to introduce some more soon. This time I definitely want fish that will swim out in the open. I have fish that hug the rockwork, that sit on the sand and one that hides in a hole in the sand, I really need some bold fishies that aren't shy!
The new corals have been fixed in place and are looking great, I just hope I can keep them looking as good. I had to move the Lobophyllia as Lurch the conch kept barging past it and knocking it over, it's well away from the Acanthastrea now so there'll definitely be no coral warfare between those two.
Also, and try not to laugh too much, but I managed to take a quick video of Gordon the Whitecap goby and Al, his pistol shrimp partner. Al had decided to rework the 'wall' yet again giving me the best chance of capturing them on camera. Unfortunately I had to position the camera downwards to see into the hole so there is some glass distortion and I've never taken a video in my life so there's that, lol! Still you can see that they are alive and doing their thing.
Whitecap goby & Pistol shrimp
Today we discovered something new and pretty awesome in the tank, a teeny tiny bivalve attached to the side of the Lobophyllia. It measures just 3mm across and opens and closes so it's still living. Up close you can clearly see the inhalant and exhalant siphons suggesting that it's a harmless filter feeder. I just hope that it can find enough to sustain itself in my tank. I've no idea of an ID any further than it may be a cockle of some sorts. So cool, I love finding new inhabitants in my tank.
A new month and a new FTS. Besides a few new corals not that much has changed really. The Stylophora is showing some nice growth, the Lobophyllia and Acanthastrea look good, the zoanthids are, err, surviving. I think that all the nudibranchs have gone now and the remaining heads are opening up once again, I did lose a few of the orange ones that were on top of the rock, they simply melted away. Too much light/too little light/too much flow/too little flow? Who knows?? To be honest I've never really been that successful with zoas, perhaps the water is too clean? I'm considering feeding some coral foods to see if it helps them at all.
Acro #1 looks the same, it was knocked off the rockwork by a naughty hermit crab and when I stuck it back down it was in a slightly different orientation so it's difficult to tell if there has been any growth or not. Acro #2 has shown a tiny bit of growth and the damaged tips on the lower left-hand branches have regrown. I do think that they have lost a little colour though, another reason to try feeding perhaps, plus the nitrates and phosphates are still undetectable which according to current thinking is not ideal for SPS these days.
Since the Pink Streaked wrasse was added the Nudus gobies and Red Striped goby have moved to the front right of the tank. I get to see a lot more of them now which is really great. The tank has settled down nicely again. I need to relocate the Lobophyllia as Lurch the conch keeps knocking it to the left in his quest to clean the lower rocks. I am also thinking of adding a plating coral to the rock that sits above the pistol shrimp and Whitecap's home (I've seen them again today btw, two days on the trot I think that's a record, lol!) in order to give the entrance to the burrow a bit of shade, I think that will help them to feel more comfortable and hopefully they will become more visible. At the moment the lighting is really too bright for them.
I've been trying to get some shots of the Possum and Pink Streaked wrasse but it's proving difficult as they don't sit still like the gobies do. I will keep trying. Oh and last but not least Crystal the Bruun's cleaner shrimp shed her exoskeleton again last night so she seems fine too.
Not a whole lot to report regarding the gobies and pistol shrimp over the last couple of days. The Whitecap is nowhere to be found during the day but it does venture out after the lights go down and roams the tank. It looks so tiny and seems to be easily buffeted by the flow, I am yet to see it eat anything. There have been no sightings of the shrimp at all and no pistol shots heard either, I can't decide if I am more worried for the fish or the shrimp now. The T. nudus gobies are also still unsettled although #1 (Hop) has started to eat again, #2 (Skip) is still on hunger strike. Edna the possum wrasse and Candy the Red Striped goby seem completely unfazed by the new additions, nothing puts them off their food, lol!
With all this upheaval I have failed to mention that on Saturday I added a few more corals to the tank. A couple of small Acropora sp. frags and a single head of Lobophyllia sp. I haven't taken any photos of them before today as I have been avoiding cleaning the glass in fear of causing even more disturbance to the fishy occupants. I decided to risk it today however.
