Is it normal that my fish float at the bottom of my tank?
Hey this is a questtion or call for advice to anyone who knows a bit about fish....Basically my fish keeps lying on the bottom of the tank with it's top fin down....I went to a local pet store and the told me it was maybe suffocating, so I fiddled around with my pump/filoter so it was letting mor oxygen into the tank and it still does it. Anyone know why?? Advice would be greatly welcomed as I have lost like 3 fish due to this weird problem. Is it normal? :( Thanks
