I have a tussle filefish. A couple of weeks ago I noticed a small bump on the left side of his mouth. Now his whole mouth has swollen up it looks like he swallowed a balloon. All my parameters are perfect. He is eating but I don't know for how long can anyone please help me. I have a 80g tank with 10 other fish im not going to list them because i'm in a hurry not of them are aggressive please help i have included some pics.:help:
