Tumor-like thing on a clownfish

[sikorskys]

Have found this today. It's round and the size of a small fish food pellet, 1mm or so. Every other fish looks fine ATM.

What could it be?

Clowns are two years old, but I've added helmon and scopas tang a week ago (without QT).

at this point being only 1 i would just observe...but be ready to move to qt and treat with the trifecta if it opens up or spreads.

Thank you. I probably should move it to QT before it opens.

Thank you. I probably should move it to QT before it opens.

What ended up happening? Is the fish doing well? My clownfish seems to have developed one as well
