Problem- Red Tail Shark has wound on it head it seems like... It almost looks whiteish... I know its not ick.. none of my other fish has that on them and its only on that one spot on the shark.

Setup- 20 Gallon Tank, 2 Rainbow fish, 1 Killie Fish, 3 Otocinclus Catfish...

There is a little cave type thing for him to hide... all artifical plants except for 1... I also got drift wood in there... Please help me out so i know whats wrong with my red tail... I thought it would be other way around with my other fish having wounds, but they are perfectly fine.!!!
