I put 6 green chromis in a week ago. They were beautifully schooling together the first day! Woke up in the morning and one had disappeared - I still haven't found his body. I was gone from home for about 3 hours and when I came home another one was dead, laying on it's side on the sand. About an hour later I noticed another one hovering above the sand with nicks on it's side. By the time I got the QT ready to isolate him in he died too. Now I'm left with 3, one of them quite a bit bigger than the other 2, but these 3 seem to be getting along just fine. I would like to get rid of the big one but I can't catch him. I wish I had skipped them altogether.
