One of my zebra danios has a fat stomach, only on the bottom though, but from I can see from the fast swimming, is that the scales are raised slightly. Though, I've also known from my zebra danios that one of them is a female (from what I can tell) because all my other ones swarm around her and look like they're trying to breed her and she was fat at one point(at least I think this is the one >_<) before for a long time then got skinny again (I'm assuming my other fish ate the eggs cuz I've not seen them) but I just got through with another one of my danios with dropsy and it's just striking that question to me. It's just staying in one corner of the tank, my other ones are swimming around it to try to get it to follow them, which it does for a bit, then just goes back to staying in the corner.
