White bumps around clownfish bump

[Michael Tang G]

One of my clownfish is showing white bumps around its mouth and I’m not sure what it is. I started noticing the white around its mouth yesterday but today there’s a pretty pronounced bump. Any idea what it is and how I should treat it if needed? Attached photos

Also noting that she’s breathing/swimming/eating fine at this time. Don’t see anything on the other clown/fish.
