I don't know much about fish diseases, because good thing I haven't had to deal with many. Now I have a platy who looks very very bloated all of a sudden (he's male, so not pregnancy) and his scales are protruding. I think I remember reading something about this. I'm wondering if it's contagious? The rest of the fish are fine, and even he was swimming around just fine earlier, but for the past few hours he hasn't moved much. I'm suspecting over-feeding may have triggered it. Should I be expecting this to be contagious at all? Thanks
