Hi, I have two rosy barbs, there used to be three, but one died a couple months ago. One of the two that I have right now is exhibiting some very strange behavior. It'll belly flop sometimes, and just stand still vertically in a plant or something. Sometimes I think its dead, but then it will randomly start swimming normally for a few seconds. Or it will just let it self go and just float in circles in the water. I suppose it looks a little bloated. But I'm really worried about it. Any ideas what could be wrong with it?
