faint white patch on clown

yeah, the spots gone and he has more energy then the other clown, hes trying to host in my zoanthid, and also has been doing the same rubbing his side thing on my rock, I figure he wont hurt himself, and you the psuedochromis is very territorial, but hes pretty peaceful otherwise, always swimming around too, hes more content fighting his reflection then the clowns, so hopefully he wont fight with w/e else I eventually add, I really want a goby after my yellow headed sleeper goby darted into something and killed himself one night, thought about getting a neon blue cleaner goby
