Continued rotten, rotten luck with fish.
I picked up a very nice black ocellaris clown for this tank. It died. At a loss. I tested the water, no ammonia, no nitrites, not even nitrates. Firefish is doing great! He never picks on anybody either. Very mild fish.
I may try another LFS, as there seems to be no consistent pattern with the fish that I get from the one I usually go to. They look great when I get them. I'm not stupid, I don't buy unhealthy looking fish. I mean, sheesh, I'm keeping a spotted mandarin and a panda goby healthy and happy. The sps in my Biocube are growing really well and my zoas in that tank are spreading. The elegance is extended and bigger, and my duncan grows like a weed. I don't know. As much as I love that LFS, I may try another place, especially for fish.
My dottyback is doing extremely well in the old 8g. I got him from the same place where I get my acans and Caribbean corals. This guy will get what I want, I think too. I also think he and I keep our water in more similar parameters. Perhaps the other LFS keeps her salinity a bit lower. I keep mine for sps, so it's at like 1.026. I drip-acclimate my fish carefully, but you never know.
Lots of factors, but honestly, I know it's not me. My stylos and birdsnest speak volumes on the health of this tank.
