Brooklynella or something else?

I noticed this popping up on one of my clowns. Need help identifying what disease/parasite this is and how to treat

She won’t sit still for a picture of course. I have another clown (they’re a pair) a wrasse, an a gramma that have been in the tank for almost a year. And then a tailspot goby I added about a month ago

Mouth lesions in clowns is often from grappling with the other fish in a pair. Sometimes, pairs break down, or the fish have short spats. If the fish is still eating well and has no other symptoms, I think the risk of treating it for a possibly non-existent disease and it’s possible side effects is greater that simply watching it closely for now.

Makes sense to me. I haven’t noticed any fighting or spats but I’ll keep an eye out.

If it’s something like Brook, will it become obvious when it’s time to pull and QT? Would you recommend having everything needed for the QT (medications and all)? And if I have to QT, do I need to QT the entire tank? Or just the clowns?

If it’s Brook, it will spread as a general mucus all over its body. Swimming will become “stilted” and it will stop eating. You’ll need to intercede before it reaches that point though.
