In the midst of dealing with my diatoms, I noticed that my female clown has a "mole" on her face. It wasn't there when I got her about a week ago.

It is slightly redder than her normal color and protrudes from her face below the corner of her mouth. I'll try to post a pic shortly, but are clowns known to get any kinds of parasites? Wondering if she maybe just scraped her face or if it's something growing on her. She is eating and acting normal, has no other discoloration or swelling. Just looking for ideas.
