This is my first attempt at zooanthids but I'm afraid I'm failing: I have a 7 gal tank on my desk at work that I had set up running for 2 months before I added some zoos. They seemed pretty happy for about 2 weeks then started staying closed more and more often. I got concerned that maybe I had a pest so I gave them (and other rocks) a wash in ReVive but nothing came off. I've kept an eye on them and haven't been able to spot any pests (checking throughout the day and after lights off). My water parameters are pretty stable at Amm-0 Nitrate-0 Nitrite-0 SG-1.022 Temp- ~78. There is a powerhead that provides moderate flow (I've tried moving the zoos to areas of higher and lower flow). I feed the tank a couple of mLs of PhytoGold-S phytoplankton every couple of days. I've tried 2 lights- I started with a 14W 8 inch fluorescent (they were open in the LFS in low lighting) then tried 6700k with ColorMax T5s. It's now been 2.5 months since I've seen the zoos open- normally I would assume something not feeding that long would be dead, but they're still there- not disintegrating, they're even still purple. There's not much else in the tank (1 sponge and 1 mushroom- 5 'sexy shrimp', 1 porcelain crab, and 3 tonga snails). I'm really at a loss for what could be going on.
Any help, ideas, etc. would be greatly appreciated.
