Weird wound on clownfish

[maxs]

Hey guys! I noticed a decent sized white dot on my female clown about a month ago. I’ve been keeping a very close eye on it the past month and it hasn’t grown in size and it isn’t raised, it’s completely flat. Almost like dry scales? She hasn’t been rubbing it on rocks or acting weird at all. Still a very very good eater and no irregular stools. Was just wondering if anyone has a clue what this could be? Maybe a bite wound? I’m gonna try to get a better picture with white lights. Thanks!

Tank mates are another male clown, a purple fire fish, and yellow watch man goby. With some inverts and clean up crew. Tank is is 30 gallons

It's too difficult to tell. Probably not a wound if the fish has had it for a month.
