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.
I love getting out the magnifying glass and looking at the small stuff, there's always something new and cool to discover.
So far the corals (and clam) that I have purchased from my (sort of) LFSs have arrived with 'extras'. Aiptasia, nudibranchs, pyramid snails & red bugs. The corals I have mail ordered from Reefworks however have been hitchhiker-free, so it was a kind of a no-brainer who to choose for my next additions. On Friday I took delivery of some lovely new corals. A beautiful frag of Oxypora sp., so well encrusted that the frag plug was completely hidden, it's my new favourite coral. A frag of Cyphastrea sp. "Meteor Shower", also well encrusted although I would have preferred to have been able to remove the frag plug entirely for positioning onto the rockwork. It looks kind of unnatural at the moment but hopefully it will 'grow in' given time. I also received a frag of Acropora sp. "Red Dragon", and a frag of Acropora sp. with purple tips (but is currently not purple at the moment), plus a frag of Red Tuxedo zoanthids. The zoas are still settling in so I don't have a photo of them yet and the I'm still working out how to take a decent shot of the "Red Dragon" (the bloomin' Welsh Dresser gets in the way. It's going to have to go, lol!).
Whilst I had the camera out I snapped a few other shots, more to follow including a FTS later in the week. Acropora sp. #2 that I treated for red bugs is now looking much happier with good PE. Acropora sp. #3 with the blisters is actually showing some improvement, a couple of the blisters have burst and the wounds are healing nicely. I think it's on the up and up now.
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!
It's four months since this little tank was set up and all seems to be going really well. Almost a bit too well actually, I'm expecting something to go wrong at any moment, it's usually the way. I'm keeping a close eye on the water parameters now that I have added a few more corals. In the past I have really struggled to keep the alkalinity and calcium levels at appropriate levels even with the use of a calcium reactor and kalkstirrer. As soon as it was pumped in it was sucked up by the corals and clams. This time round I'm hoping to maintain good levels with careful dosing. The parameters today were:
The above were tested using a refractometer, Salifert test kits and a Hanna pocket checker for the phosphate. I'm fairly sure that my phosphate level is not really zero but it must be pretty low and there is very little in the way of nuisance algae growth in the tank apart from a bit of furriness on the rocks. I do not know what the furriness is but it doesn't look too unsightly and stays short. In any case there seems to be less of it now. The macro algae growth in the refugium has been disappointing to date, considering the lack of nutrients I suppose it's not entirely surprising. As long as the reason is not down to a lack of flow or lighting, time will tell, I can't imagine this situation will last for long. I've started dosing a small amount of Reef Roids and KZ Sponge Power recently so they may affect the levels in the future.
You'd think that over 4 months I'd de familiar with all the livestock in my tank, well no actually. A couple of days ago I noticed that the Seriatopora had retracted its polyps and on closer inspection I discovered a small crab sitting at it's base. Where on earth had he suddenly popped up from?? I highly doubt that he came in on any of the SPS frags as they are too small to conceal a crab, I suppose it could have hitched a ride in on the zoanthid rock but the most likely explanation was that it was hidden in the live rock when it was first added. It doesn't look like it's chowing down on coral flesh (at the moment, heh!) so I'll leave it be for the time being and watch and wait. I hope it behaves itself or we'll be having some fun and games with extrication later on.
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.
It's all gone quiet on the pistol shrimp and Whitecap goby front, no positive sightings since Wednesday the 25th and no new burrow holes have appeared in the sand either. Still apart from their absence the tank looks to be doing OK. Parameters are within normal ranges and the corals that I have look fine, time for some new additions methinks.
I still really want to add an Acropora colony with a commensal crab hidden in amongst the branches but all the colonies I have seen have really large bases which would be difficult to find places for on my rockwork. I could cut them down I suppose but it would be hard to do without damaging the coral, not to mention freaking out the crab, so I decided yet again to stick to small frags only. Unfortunately the tank is going to look pretty empty for ages whilst they grow out and I will have to make sure that I stay strong and don't get tempted to fill in the empty gaps with extra corals. So anyway on Saturday I chose a beautiful green frag of Acropora formosa (I think) and a frag of Seriatopora hystrix. Additionally I perhaps rather foolishly decided to purchase another fish, one that will hopefully be on display (eventually) for a bit more time than my current fish stock. I settled on a small Pink-Streaked wrasse who I was assured by the LFS was not just a pretty fish but also functional predator of the troublesome red bugs etc. I don't have any of those in my tank at the moment....but you never know.
Needless to say the tank is now in fishy turmoil again. The Nudus gobies have moved out of their new (version 2) home and even Candy the Red Striped goby has changed her usual perching spot. Sigh! Interestingly Edna the Possum wrasse doesn't see bothered at all and seems to be ignoring the new fish. Who knows what the Whitecap is thinking imprisoned under the rockwork (alive I hope!). I must point out though that the Pink Streaked wrasse does not appear to be aggressive at all to any of the resident fish, she has spent all of today cowering in the right-hand back corner of the tank.
I think that's it for new fish additions for a while, the current occupants need to settle down and chill out a bit.
