I have a paradise gourami who has been thriving for at least a month and is very friendly. A while ago he got a little chunk bitten out of his side right before his tail fin starts, but never seemed to care, and does not seem so now. However, I noticed today that it looks like someone else has picked on it, and I can see a little white thing in there that I am hoping isn't bone. It has never looked infected and doesn't now, but it does look irritated. Does anyone know if there is anything I can put in the water to help it heal? It does not look like it has healed at all since he got it, which was at least a month ago.
