See I thought that too Obscurereef, but all my other fish are swimming fine down in the bottom without ever coming up. I got good water movement on top and an open top tank. My Clown is still on top.
Boreddome, I wouldn't be worried as long as it's eating and swimming fine. I was worried about my Clown until I read many online reports of other peoples Clowns doing the same thing. I guess it's just what they do sometimes! I don't know why and it is kind of disheartening being I want to see him swim the tank.
Fish Sticks, the best thing you can do with your dead fish.
