I'm not sure, but that's a beautiful purple & yellow fish! What type if you don't mind me asking? Sorry for not being able to help.

Looks like an anthias and could it have been fighting with the other clown?

That was the only thing I could think of! My two clowns fought often to establish dominance. Some of the aggression appeared very hostile to me.

No worries lol.
It's a Bartlett Anthias whom my daughter has named Pinker lol. Very active fish always swimming in front of the tank when the lights are on

I haven't noticed them ever fighting. A few weeks ago this same clown looked like a small part of his mouth was swollen and white but then it went away

My banded coral shrimp has been a little aggressive lately...well since he's gotten a bit bigger anyways, could it be him nipping at him? This particular clown is rather lazy...likes to stay on the sand in one spot and cruise until it's feeding time

Yeah I know when mine first fought for dominance the other got pretty ripped up
