Question
i have five different kinds of goldfish and fed them little pieces of bread now one of them seems to be floating at the top of the tank but he is still breathing.the stomach is bloated and hard. is it dyeing or pregnant?please help me!!

Answer
Well, I think it sounds as if your fish has ingested too much air. You should try to feed your fish a food which sinks. Fast the fish for a day a week and see if the problem gets better. This is a common problem with goldfish and is why I do not prefer them at all, sorry. Bread really isn't a good meal either way though. See if this helps, it should and as long as the fish continues to get better and is active and not stressed, it should make it. Good luck
