So I woke up this morning to discover my cowfish dead in my BTA anemone's mouth. I have read that cowfish can drop poison when they die. I have changed out all carbon and am doing a 50% water change. Anything else I can do to minimize the effect? The two have also lived together peacefully for over a month. I also had a cowfish and an anemone in my last tank and they did fine together for over a year. Is it common that anemones eat the slower moving cowfish? Do you all think this was an isolated incident and that I can get another cowfish and have him be ok?
