Is it possible that he rubbed it raw and its not fungus ?
Thats sucks. I was hoping it wasnt health related. Almost looked similar to what polys do to their nostrils.Personally never heard of Arowana rubbing their barbel's raw but bitten off. It looks like fungus with the cotton appearance.

Salt and water changes. That or med like api fungus cure.
The Pimafix is working well, it doesn't look as "cottony". Still keeping up with the dosing and will get a nice WC this weekend.
