i dont know if this is a disease so im going to put it in the betta forum, but my betta is constantly at the surface, you may think that is no biggy, but it seems that he cant swim downwards. he tries but hes like a ballon filled with helium and your trying to make it go underwater. then if he doesnt move but just lazes there, he begins to go horizontal. one side goes faces down while the other faces up, please help me!
