Hey,
I purchased an anemone (not sure what kind, it was cheap- white with little purple tips) about 7 months ago to put into my nano tank. It has been doing fine until 3 weeks ago when it started floating around the tank. It will occasionally hook up with rock but it rarley stays there. I have live rock in my tank along with a peppermint shrimp and a few turbo snails. I had a damselfish in there but he gave hinself a concusion and died (got scared the other day and hit the lid really hard, couldn't revive him ) Am I doing something wrong? I have tested the water and its just fine. Any tips?
