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?!
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.
Just a quick snap of the Balanophyllia taken today with my iPhone after lights out. I've settled in to a routine of feeding this coral once a day now. It's not fussy what it eats, PE mysis, Krill, clam and mussels (which seems kind of wrong since there is a live mussel located right below it!) are all eagerly consumed.
I've been really pleased with the progression of the tank recently, the fish seem settled with no argy-bargy between them, coral colouration continues to improve with each week and things are generally looking healthy. I hope by saying that I've not just jinxed everything now.
As a consequence I have been on the look out for a few more corals to add a bit of extra interest to the tank. It's proven hard to source the last few bits from my wish list as they don't seem to be readily available or the pieces I've come across in the shops are just too big to squeeze in my tank. Regular readers (if there are any out there? Ha ha!) will know that I've been trying to stick to small frags so that I can enjoy watching them 'grow in', plus buying aquacultured corals has always got to be a good thing, right? After 7 months of keeping my eye out I resorted to shopping online (my second favourite pastime). I never thought I would actually take the chance of buying corals online but so far my experience of it has been all great with no losses to date.
Yesterday the postman brought me not one, but two packages, it was a very exciting day.
The first package contained 3 corals. A Balanophyllia sp., possibly my new favourite coral. This is non-photosynthetic and will require feeding by hand but it is so very, very pretty. I had originally wanted to source a small colony of sun coral (Tubastrea sp.), as I've kept those in the past and found them easy to care for but have not seen any for sale, They used to be regularly available but not any more it seems. Anyway this species is very similar (and fits in the small size theme) so I decided to give it a go. My research has suggested that they only extend their feeding tentacles at night but this one seems happy to open up no matter whatever the time of day which is wonderful, more time for me to admire it! As a bonus there is a mussel attached at the base, although I haven't ascertained if it's still living or not. I do hope so but keeping it that way may prove difficult as it's a filter feeder.
Check out all those nematocysts!
Then came a baby plate coral, now I knew that I wanted an LPS coral with swaying tentacles and had originally considered a Euphyllia sp. but I know these can get very large over time so I finally settled on a plate coral. When I saw this baby one available I knew that I wouldn't have a better opportunity to purchase one, it really is tiny measuring just 2cm across when the tentacles are expanded. Normally these corals are free living on sandy or muddy substrates but this one presently has a 'stalk' and when it arrived was glued to a flat frag plug. Unfortunately the frag plug was covered in tiny Aiptasia so it just had to go. The base was duely chopped off along with as much of the original superglue as I dared (and there was a LOT!), then it was fixed it onto a spare piece of rock I had in the sump (I just knew that I'd find a use for that rock eventually, lol!). Now I am hoping that this coral is indeed a long tentacle plate coral, Heliofungia actiniformis and not a very small branch of a torch coral, Euphyllia glabrescens. They do look rather similar when small. I guess time will tell, if it grows and detaches from the base to become free living then it'll be a plate coral, if it develops new branches then it's not!
The final part of this order was a Sunny D zoanthid (plus a baby bud), during transit the polyp had worked itself free of the frag plug so clearly it had been fragged very recently. My first response was one of annoyance but as I hate the look of frag plugs in general it proved fortuitous, it was a simple matter to dab a bit of glue to the base of the polyp and fix it to my live rock. It opened up within a few hours of introduction and is still there today so hopefully it'll survive. I think it's fair to say I'm now a fan of zoanthids, I'm up to 7 different types now, how did that happen?! ;o)
My second online order came all the way from France, how brave was that!! Ever since I added my first gorgonian I knew that I wanted to introduce at least one other species. I had been waiting to purchase the purple frilly gorgonian that Reefworks supply but as it hasn't been available for months I started searching elsewhere. Sadly gorgonians seem to be a bit of an afterthought at most LFS I have visited. The SPS corals are lined up neatly in tanks but the gorgonians seem to be plonked in without any care to their wellbeing at all, most ending up lying on their sides and being stung by something more aggressive resulting in stripped branches or worse. Fortunately for me I discovered Eco-Gorgs, sustainably-produced aquarium sized Carribbean gorgonians, perfect for me and only a few clicks away. OK, admittedly a bit of a journey was required to get them to my tank but worth the chance i thought.
First in my basket was a small frag of Plexaurella sp. and very fluffy looking it is too.
This was followed swiftly by Isis hippuris, though I have to say it doesn't look anything like images of this species online but what do I know?
...and lastly Muricea elongata because it seemed a shame to only order just 2 corals when they were coming so far. This is the only one that has not fully extended all it's polyps yet. I had to leave all 3 gorgonians on the sand for a few hours after acclimation whilst I went out and when I got back this one had been knocked over, typical! There seems to be a bubbling issue with the two branches that had been in contact with the sand. Fingers crossed it will recover in a few days time.
That's it for the time being, I'll try for some better shots of the new corals later on in the week when they've fully settled in and maybe even a new FTS. If you've managed to read all the way to the bottom of this post then top marks, you must be a sucker for punishment!
