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?!
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.

Time for another ICP analysis to see how things stand with the Tin pollution as of 29th August 2017.
I'm pretty happy with those results, just a tiny bit more tweaking required and everything will be right where I want it to be. The Tin has finally fallen to an acceptable level and hopefully will continue to fall until it's undetectable. The Calcium dosage needs increasing and the iodine dosage reduced a touch. One lesson learnt here is that the test kit used to monitor the iodine levels in between ICP tests (Salifert) is a complete waste of time. The iodine level in the tank has gone from 0 (mid April) to 74ug/l (end of August) and in all that time the test has registered nothing more than the faintest hint of colour which equates to less than 0.01ppm (10ug/l). I knew before I started that the home test kits for iodine were considered inaccurate but I didn't realise they were quite that useless (well the Salifert test anyway). I won't bother to use it again.
I'll sign off with an updated FTS (as of today) this time featuring a beautiful splash of yellow. My Halichoeres chrysus wrasse is pretty hard to miss don't you think. When I introduced her I had assumed that she was actually a he but I have been informed that these wrasses are all born female. So she now goes by the name of Rei instead of Ray and she will remain female for a while yet before making the changing to male on adulthood.
Firstly, time to update the fish list.
Sadly the Red Spot cardinalfish are no more, thanks in part to the tiny but rather mean Red Spotted goby. There were no more jumpers but the three that remained never really settled no matter how much I tried to feed them. They vanished one by one until there were none left, the last disappearing on the 4th August. I have to say that the tank looks empty without them but I will not be replacing them as I feel they are simply too sensitive for this sized tank especially with its current fishy occupants.
In addition to the loss of the cardinals, one of the Red Spotted gobies also vanished. The smaller of the two and not, I might add, the mean one. Sigh! Perhaps he had got bullied too?
At that point the fish list consisted of Candy the Red Striped goby, Hop & Skip the Nudus gobies (although I hardly ever see them any more), Edna the Possum wrasse, Kylie the Pink Streaked wrasse and Rocket the remaining Red Spotted goby. It was time for something new and this time I decided I wanted a bold and above all easy to keep fish. As I'm rather fond of wrasses I'm afraid to say I bent my rule of staying with small fish only. I opted to add a juvenile Yellow wrasse, Halichoeres chrysus. What a ray of sunshine this fish is, certainly not one to blend in with the rockwork.
He was introduced on the 21st August at 4pm and as expected, immediately dived into the sand. He was up and about just after 9am the following morning. After 30 minutes of orientation he began picking tidbits off the rockwork/sand and when it came to feeding time there was no hesitation or fussiness. He ate everything offered without a second thought. Hmm this fish is going to grow fast I think (oh dear, what did I say about never upgrading tanks ever again...).
Ray, as he is now known, is a lovely fish. He's settled into a routine of getting up around 8.30am and going to bed at just before 7pm, he sleeps in the same area of sand every night. During the day he's constantly on the hunt for pods/worms/whatever else takes his fancy and if I approach the tank he comes up to say hello rather than hiding in a cave, now that's a refreshing change! Fortunately, he's not tried to eat Crystal the Bruun's cleaner shrimp yet and I hope he never does (always a risk with these fish). So far the easiest trouble free introduction ever.
As for the corals, growth is steady and colouration improving. I have managed to resist the temptation to add anything new although I do keep looking, lol. I am a little concerned for the Red Tuxedo zoanthids, I fear that they are suffering from the bacterial infection known as zoa pox. If I am correct I know this could spell disaster for my entire zoanthid collection but as they have encrusted onto the rockwork directly I am a bit stuck. To dip them would mean a complete strip down of the right-hand rock pile which is something I'm not prepared to do at this point (or ever if I'm entirely honest). I am simply watching and waiting and hoping it doesn't spread.
I am working on updating all the coral photos and am almost there bar a few.
Charlie climbed to the top of the refugium to say hello to me this morning. I discovered her sitting on top of the thick mat of algae. Oh my, she's grown a lot! So is clearly finding enough to eat down there. :o)
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.
So, Benji the hermit crab is just minding his own business cleaning off the algae growing on Lurch the conch's shell and wham, Lurch's operculum shoots out and knocks him off in the blink of an eye. I guess Lurch didn't want his shell cleaning after all, lol!
Here we have a Cerith trying to hide amongst the zoanthids, but come on, that blinding white shell is not making it easy is it? Lol! Perhaps if it didn't spend weeks/months 'sleeping' under the sand things might be different. I'm just glad to know that he (or she) is still in the land of the living.
Well I never!! I reported in a diary post on the 21st July that the "King Midas" zoanthids were beyond all hope but it seems I may have been a tiny bit hasty....
To recap I introduced these zoanthids on the 25th June and intially left them on the sand for a week whilst I decided what to do with them, they seemed fine and opened up beautifully so I fixed them to the rockwork on the right-hand side of the tank. After that they promptly refused to open up again. After a week had passed with no improvement I decided to put them back on the sand again and in a couple of days they began to recover. Then I chose another spot on the rock not that far from where they were sitting on the sand and fixed them down again. They closed up again and began to shrink away. What the...?! So frustrating!!
For all intents and purposes I gave up on them as I didn't really know what to do anymore. There aren't many free spots left in the tank for corals these days. Finally when there was barely anything left on the frag plug I pulled it off the rock fully intending to chuck it away but I just couldn't bring myself to do it. You couldn't call them zoanthids really but there were some tiny blobs of flesh still attached, so back to the sand they went. This time I left them in amongst the 'shell graveyard' (the is a pile of spare shells on the sand front right-hand corner of the tank that the hermit crabs have either moved out of or will possibly utilise in the future (and the amphipods just love to play hide and seek in them)).
After a while the blobs started to show short some stubby tentacles and, knock me down with a feather, they began to resemble tiny zoas again. I've absolutely no idea what I'm going to do with them now, I'm not going to mess around with them so I guess they can stay where they are for the time begin. Fingers crossed that the hermits/snails won't bash them around too much when they going foraging for food.
