Firstly another equipment change to report. I finally decided to change out the Beamswork EVO refugium light for a Kessil H80 Tuna flora. I had been considering replacing it for quite a while now, not because I was unhappy with the light but because the metal stand was rusting in all four corners where it sits on the top of the refugium. I'm not sure if this has caused any metal contamination in the tank yet or not but I wasn't happy with the situation so it had to go. The reason I opted for the Kessil is because it's pretty much the only light that I could find small enough to fit over the refugium, everything else was either too big/long and would have caused a huge light overspill issue or excess heat in the small sump area. To combat at least some of the light spill produced by the H80 I have added a small piece of black acrylic sheet between it and rest of the sump. The red light is something that does take a bit of getting used to but if the macro algae grows well under it then I'm happy, time will tell.
Now for a Fauna Marin Skimbreeze update. The FM media lasted two and a half weeks before needing to be replaced, about the same amount of time as the most recent ATI 1l disposable unit. I'm not that keen on the design of this reactor itself as air is preferentially pulled from the side the outlet tube sits (as can be seen in the photo below). So when changing out the reactor some media is still unused. I think I will try rotating the cylinder next time to see if I can reduce the problem. To refill the reactor I used the Spherasorb media, it looks exactly the same as the FM stuff but costs a lot less.
As for the livestock well everything is ticking along. Acropora growth is slow to nonexistent thanks to the red bugs but at least they are not dying. The exception to this is the A. hyacinthus which seems fine (with a rather odd growth shape it must be said), I've accidentally fragged it with the algae magnet a couple of times now because it's growing too close to the front glass.
The Utter chaos zoanthids are becoming annoying as they keep detaching and floating around the tank ending up in spots where I don't want them in or sucked on to the powerheads. Since I don't have anywhere to place frags (and hate the look of frag racks in the DT) I've chucked the loose ones I've found so far.
The sun coral is still releasing planulae and I keep finding baby polyps popping all over the tank. The more I look the more I can spot, they've even settled out on the clam shell. The larvae are fascinating to watch, tiny orange tear shaped blobs that wiggle around the tank until they find somewhere to settle out. It's very cool!
As for the Balanophyllia now living down in the sump, I can't decide if it's doing better or worse. There is one thing though, I happened to knock it over whilst trying to feed it and when I set it straight again I noticed it has some tentacles poking out the back, my initial response was Oh ****! Aiptasia!! But on closer inspection it actually looks like a baby Balano bud. I'm not sure if this a good sign or a bad one? Is it failing so badly that it's sending out buds as a last ditch attempt to survive?? I surely hope not.
I'll sign off with a few photos.
And finally a FTS..
I first noticed that Acropora #4 was suffering from slow tissue necrosis (STN) in July '17. It was receding at the underside of the base but, as the top half looked good and was growing, I chose to ignore it in the hopes that it would eventually stop. Sadly it did not and in fact continued to the point where I had no other option other than fragging the coral. Since the branches were still short and stubby this proved somewhat tricky tricky to do. In the end I was left with just three tiny branch tips. The lesson learned here is that it's never a good idea to stick your head in the sand and ignore a coral issue (especially for 6 long months *cough*). I do not really know what caused the STN in the first place but the base was fixed into a recess in the rock so perhaps it was down to poor flow?
Talking of encrusted bases, remember Acropora (#2), the one that I tried to remove in June '17 after discovering that red bugs were still present on it? Well, the base is still ticking along nicely, growth upwards is slow but there is at least some growth oh and and it's started fighting with the Montipora sp. to the left of it.
On a happier note I'm discovering more and more sun coral larvae dotted about the tank. I expect most will not survive as they have settled quite close to other corals (there's not much real estate left these days) and will probably be quickly overgrown. This is probably a good thing else in the future I will have to spend all my free time feeding them.
Here's another shot of the Heliofungia from the other side taken during a water change, the only time the top lifts up enough to view the baby buds growing underneath.
Finally I'll sign off with a few other random shots, including a (now) rare view of Skip the Nudus goby.
It's been almost 5 months since I first discovered the sun coral had released planula larvae and I am happy to report that they are all still all alive and kicking, if still quite small. One is actually doing much better than the rest, mainly because it settled in a better location enabling it to catch more food. It's actually big enough to feed directly now so I've started offering it tiny bits of mysis and krill. Unfortunately the zoanthids growing below have begun to obscure the view of it from the front so it's becoming quite difficult to photograph. I poke them with a pipette but they are opening right back up again before I've even managed to grab and point the camera. Eventually I expect they will grow right up the rock and maybe smother the sun coral completely which would be a pity, perhaps by then it'll be large enough to fight back?
Additionally I discovered today that the original Sun coral has been at it again! There are at least five more new babies dotted about the tank now and I'm sure there are probably more hidden away in there too. It must have happened fairly recently because these larvae haven't even developed any tentacles yet. The one below runs the risk of being overgrown by the Montipora above in a very short space of time.
As for the baby Heliofungia buds, they continue to do well and in fact the entire underside of the coral is ringed by them now. I am not exactly sure how many there are at this point but probably at least six. They show no sign of detaching yet.
Just prior to the skimmer failure I sent off water samples for yet another ICP analysis. The results of which are shown in the link below:
100%! Apparently I have a full house, everything is in balance although to be honest the salinity is a bit higher than I would like. I must try harder. The conductivity probe had drifted out of calibration. The tin contamination is gone at last but I seem to have a reading for iron this time round. The only change between now and the last test is that I have begun to soak the fish food in a vitamin supplement, I wonder if that’s the source? Something (else) to keep an eye on. I still can’t get much of a nitrate reading despite adding a couple more fish and feeding loads. I wonder if running the tank for 5 days without a skimmer has raised it at all?
Moving on to the corals, the warfare continues. The Favia continues to batter the Cyphastrea relentlessly. I thought it might stop once the leading edge was dead but no, the dead area seems to get larger every day. I would move the Cyphastrea if I could but firstly, it's well encrusted, and secondly I have nowhere else to put it.
Two of the Montipora sp. (#2 & 3) are now clashing with Acropora loripes and both are losing. Montipora #2 is also being hammered at the back by the Stylopora.
Despite religious feeding the Balanophyllia has still not been doing so well, It was only after I made the decision to move it that I discovered that it was receding very badly at the back where I couldn’t see. There was a white band of what I assume to be a bacterial infection at the receding edge. I relocated it to the rear of the tank but in hindsight I should probably have placed it in the sump because as soon as the Pintail wrasse were added, feeding it became nigh on impossible. They just kept stealing its food. Fortunately the Sun coral continues to do well and has grown multiple new heads. Feeding it can be a battle with the wrasse but it can be done with a little perseverance.
Moving on to the red bug problem, with no plan of attack they are obviously still present but the Acros seem to be coping with them for the time being. I fully expected the afflicted corals to be failing by now but they still have reasonable polyp extension and colour. I'm sure that they could look better as could their growth rate but at least they are not dead. The watching and waiting continues.
I've indicated some of the red bugs present on the Acropora below with red arrows there are more shown in the shot but you get the general idea.
As for the fish, Edna the Possum wrasse passed her first anniversary in the tank on December 18th and Kylie the Pink-streaked wrasse will have her first anniversary on the 28th January 2018.
A few more photos of the Pintails (Tinker and Belle) and Rei the Yellow wrasse too.
A few other random coral photos. I had hoped to have more shots to share but Christmas preparations got in the way.
Thanks for following my blog, I hope you all have a great Christmas! Hopefully I have more photos to share next week.
Another short video for today, time lapse this time. I recorded it just after the lunchtime fish feed when the lighting is whiter. The sun coral expands it's polyps a lot more in the early evening but the lighting is ramping down again (i.e. very blue) so difficult to capture.
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?!
It's been a month since I discovered some baby sun polyps in my tank. There are five that I am aware of, all are still present and correct and appear to be getting a tiny bit bigger. I am not feeding them directly so they must be catching whatever fish food or plankton that happens to pass by.
For growth comparison shots please see here.
I was studying the rock work this morning with a magnifying glass as I tend do on a regular basis (I'm weird that way) and I came across an unknown polyp on the rock work. My initial reaction on seeing suspicious tentacles waving around in the tank is generally, uh-oh here we go, Aiptasia again, but I quickly realised the colour looked wrong for it to be a glass anemone. Out came the camera for a closer look and what do you know! It's a baby polyp of, and this is where it gets tricky, either the Balanophyllia sp. or Tubastrea sp. corals, I'm not sure which. Further scouring of the rocks turned up one additional baby polyp tucked away under an overhang. There may be more hidden in there just waiting to be discovered, I will be keeping my eyes peeled.
I've had the Balanophyllia for just shy of 3 months and the Tubastrea for just under a month. It seems too soon for it to be the sun coral but I guess it could have released larvae shortly after it was introduced. I have no idea how long it takes for a baby sun coral to grow into a recognisable polyp. As you can see it's still pretty small at the moment, those are vermatid snails and spirobid worms scattered over the rocks next to it for size reference. More research is required and questions asked I think. No matter what species they turn out to be I'm very happy to have discovered them in my tank.
Hip hip hip hooray! Tubastrea have to be one of the most strikingly coloured corals and when fully extended they are truly spectacular!
I have managed to take a better shot of mine, this specimen has incredible yellow/orange tentacles with deeper orange, almost red, mouths. It's looking happy enough at the moment out on the sand but I want to try fixing it down on the rock work this weekend. The base it's attached to is fairly hefty so I'm not relishing the prospect of trying to remove it. I'm really tempted to leave it where it is but it looks unnatural sitting on the sand.
I've managed to source my final few livestock additions and I'm pretty much done now, I just need to watch and wait for the frags to grow out.
After searching for over nine months for a nice appropriately sized Tridacna maxima clam I finally broke down and ordered one from on online supplier in Germany. It was a risk I know but I just have not found any that I wished to buy from any of the UK shops I have visited and I've travelled around quite a few over the UK during that time. It's early days yet (5 days) but the clam is looking good so far, it's very responsive to movement which I'm taking to be a good sign but it has not fixed itself down to the rock work yet. My T. crocea attached in just a couple of days so I don't know if this is a bad sign or not.
The colour is amazing, blue from the front and a striking aqua green from the top. Please excuse the frag tile in the shot, I popped it in there to prevent the clam from tilting over until it had a chance to attach itself.
In addition to the clam I also ordered another Acanthastrea to contrast with the one I already have. This one is called Lava Glow and is a lovely red/orange colour.
Last but not least, I finally discovered a healthy looking smallish Sun coral colony (Tubastrea sp.) during a recent trip to Manchester. The colour of the flesh is such an intense orange that it almost looks artificial. At the moment I have it sitting on the sand whilst it settles in and I get used to the feeding routine. I understand that all the heads need feeding individually but it's really tricky reaching the smaller heads at the bottom. Even when placed on the rock work I'm not sure how I'm going to be able to reach all of the heads, I'll need to think about it very carefully.
Anyway here's a really terrible shot of it last night with flash, sorry about the nasty reflections on the glass.
Before I go I'll leave you with a few updated coral/invert/fish shots. Hopefully more will follow next week.
