Okay, so what I've observed are these following ways of sleeping:
~ At Petco sometimes I'll see a fish sort of floating on its side and I'll tap the glass and then he's fine... but then start to do it again... So I'm wondering if some fish sleep this way or do you think it means the fish isn't healthy?
~ My females do this sometimes: They'll be asleep or falling asleep and srot of seem to float up but then they catch themselves and go back down, then float again. Haha.
So my question is are these just weird sleep patterns or could it mean something's wrong with the fish? Any of you have similar experiences?
