FO TANK

[RazerCorals]

OK lets just say I have a tank that juts has live sand in it. Nothing but fish and sand. What exactly do the fish do at night? I know in freshwater they kind of float around etc. But in my reef my clown lays on the polyps and the firefish and goby go into rocks.

If you have the tank...Why don't you watch them :P J/K-LOL. Serious now, I think it would depend on the type of fish. Some are top, middle, and bottom fish. I think they may also all school together for the fact of security in numbers.

Once on ebay I saw this.., It was a 75 gallon tank with about 5 8" long fish in it and nothing else. Every picture showed all the fish together.

Hope this help!!!
