ok, I've had a zebra danio for over 6 months now (in a group of 5 zebra danios) and since day one, it had a slightly bigger tummy. Since then, its belly has grown huge. The scales lay fine, the fish even acts fine, swimming around just as much as the rest of them. It isn't from overfeeding because the rest of the fish look normal. I posted this info before, and nobody seemed to have an idea what it was, but I'm trying again. I can tell you that the danio's tummy does differ slightly from day to day. Some days it is less "lumpy" than others. I've done some research and aside from the normal dropsy, I cannot find much info on diseases which might be the culprit. I did read somewhere that the fish may be retaining eggs and cannot release them for whatever reason OR that is could be a tumor (but the day to day differences lead me to believe this isn't the culprit) and finally there is a possibility of some sort of internal infection and the bloating is from the deterioration of internal organs. I also do not think it is this last option because this perticular fish grew faster than all the rest, and since this has been happening for 6 months, I'd expect any organ deterioration to kill the danio by now. What do you guys think about it being eggs which cannot be released? Any other suggestions as to what might be causing this extreme bloating? Again, the fish is acting normal and eating well. The only problem I can see is that it is a little tougher for the danio to swim as fast as the rest, but that doesn't keep it from "leading the pack" and picking on others. Thanks guys!
