Hello Myka, I seen you started the pico tank and that's exciting! Any updates to this tank?
Hey thanks for checking in! I think you're the only one following... ha!
My last post was early November, and the Acros were starting to look pretty good again. I started seeing signs of suspected dinoflagellates around mid-November which were identified as Ostreopsis under microscope. I ignored this problem for many weeks because I was very busy. The infection was mild, so it wasn't requiring immediate attention. Just after Christmas the dino problem flared up, so it was time to do something about it. I started dosing NO3 and PO4, and hooked up a 36 watt UV sterilizer. This knocked the dinos back within 48 hours. Within a couple weeks (mid-January) there were no visual signs of dinos anymore. I still need to take a sand sample from the tank and look under the microscope again. Anyway, the Acros didn't appreciate the dinos covering them, so many of them paled out yet again. Now, the Acros are back to 8 out of 10 I'd say. I'm keeping up with NO3 and PO4 dosing. The tank sits at about 5 ppm NO3 now, and even though I dose 0.1 ppm PO4 once a day, just before adding it I get a "0" test from Hanna ULR Phosphorus checker. The tank uses up a ton of PO4.
Sometime back, maybe 2 or 3 months ago the large male Emerald Crab died. I added a new one, and shortly after I lost a few small fish. Possibly coincidence, possibly not. I had a breeding pair of Hi Fin Gobies. They used to make their way to the sump almost weekly, but they had become well-behaved and managed to keep themselves in the display for 4 weeks straight. Then 10 days after the new Emerald Crab moved in the gobies are nowhere to be found (one a few days before the other). I can't blame the Emerald Crab for sure, because there is a big bad sump crab that could easily have caught the gobies if they made their way down there again. Who knows what happened to them.
Then about 2 weeks ago the male from the breeding pair of Helfrich's Firefish disappeared. He would often hide when he was tending eggs, but he'd always come out and eat when I fed. Well this time he didn't come out for 3 days. Then he came out and he was all beat up. I tried to catch him, but he dove back down to his hidey hole, and I never saw him again. Did the Emerald Crab do it? Not sure. I know Firefish sometimes turn on each other, so maybe the female beat him up. I will try to re-pair.
So the Emerald Crab will have to go. I'm not sure if it's him or not, but it's not worth the risk.
Lastnight I added (4) Bartlett's Anthias. They are all females, but they are BIG. They bickered a bit on the QT and one got a couple bites on the fins, but they sorted it out and got along well. VERY enthusiastic feeders! So today in the display they are back to bickering, and I see three of them has some bites on the fins. There is much more aggression in the display than there was in the QT. Hopefully they settle down in the tank today. The tank looks much busier now, lots of movement. The "old" fish are acting pretty docile and in shock all these big fish just arrived! Haha. The Purple Tang is doing some Anthias chasing too, but nothing too serious.
Current stock:
(2) Onyx Clownfish, breeding
(1) Johnson's Fairy Wrasse
(1) Magma Fairy Wrasse
(1) Helfrich's Firefish, female
(4) Bartlett's Anthias, females
The camera battery is toast, I have to go buy a new one. I'll post some pics then.
