sick fantail

Question
Well, I've never seen the other fish bully the sick one, or the other way around. Also, the sick one sometimes has problems swimming - not that it can't, it just gets a little wobbly and has to move its fins to get back up. I'll add the salt though. Is there anything else I can do for it?

Answer
Hi Helen:  I would separate the poor little guy from the bully fish as that is probably what created his condition in the fist place.  If its not a goldfish I would raise the temperature to between 78-82 degrees and continue with the aquarium salt. He might also enjoy a treat of live brine shrimp...which may also help him get better... Brine shrimp are sometimes used as a laxative for fish... so fish who have trouble swimming may have a swim bladder disorder and the brine shrimp (or thawed frozen pea) will help too.... keep me posted...dave
