Ok today I turned on the light of the tank and all of the clowns were ok, same for the corys. I started to notice one of the loaches lately has been laying on his side. Which can be normal as a sleeping method. But a few minutes ago I started to get more worried. So I got the fish net and pushed him gently about half a inch and he still doesent move into a horizontal position. He is breathing because I see his gills move and his fin fan gently. Everything in the tank is ok but him, whats wrong with him?????????
