I recently brought home a purple fire fish (about a month ago) who apparently had a fungus growing on his mouth. I noticed it after I had him a couple days. It started out very small, just a "bump" on his bottom lip, but now it's a large growth. What's the best method to treat this if I can't get him out of the tank?
