Hi everyone: I was just reading an old post (about the popeyed Molly) and realized that I had a fish that died of dropsy maybe? What is dropsy? My fish had this enormous swollen belly (it looked like it was going to burst any moment) for about a month, it would appear and then disappear the next day (making me feel like it was all better). Then yesterday, I fed my fish as usual and it had the swollen belly, but everything else was fine...all of a sudden an hour later I look in the tank and the enormous belly was POPPED open! ontop of some plants like in some horror movie! I think it must have happened quickly since it was lying on top of the plants and not under a rock of something. I looked inside, there was an empty cavity (I think the other fish ate out all the insides)! What is this mystery illness? My other fish didn't have it...Or do they?
