Alright, so I have an arowana in one of my tanks, along with several decorations. I have slowly removed the larger decorations as the fish are getting bigger, but left in two rough rocks. I think that during last night, he scraped hard against them, and thus lost many scales on his back and left flesh exposed. I did a large water change and added melafix. now he seems to have a white fuzzy growth on his back where the flesh was cut. Seems like fungus, which I have never had much luck in treating. WHAT DO I DO?!?!
