Demsals are probably the most hated fish that everyone one time or another had it in there tank. My buddy just bought a damsel for his Biocube, needless to say it took out his firefish and he had to pull apart his whole tank just to fish him out. It almost made him quit the hobby. Moral of the story is DON'T BUY A DAMSEL.
Ps I have a yellow tail damsel who has been with me for 7 years, I think it's just my luck he has been behaving the way he has. Knock on wood. I hope I don't have to get rid of him.
