Its hard to see. When fish rubs its mouth or nose constantly it gets sore as you know and wears the skin away and build a blister like bump. The skin tries to regrow but keeps getting rubbed on and builds up a thick slime which I think can look like fungus. I don't know what you can do to make them stop rubbing the glass. Maybe add some tall plastic plants in the corner so the can hide behind so they feel save might help. Irridescent sharks are such a skittish fish they often injure themself banging the glass in panics. If they don't make it maybe try some bigger ones if you got to have this fish.
If they die im moving to salt, more to look at and much funner and rewarding. I appreciate your continued input. I hope that its just healing process, my other shark has the same problem but no fungus it looks good, i just dont see why they wont stop rubbing the glass trying to get out lol theyve been in the tank for 2 weeks now, and if they know its hurting them thats more of a reason to stop, hopefully its not fungus or anything like that though. I really think it is something not having to do with the healing process though because there was really excessive ammounts of it in relation to his wound and his size (3'').
