One of my red serpae tetras has what looks like a bruise (circular dark area)at the base of his adipose fin and he's starting to act a little "off". Any idea what this is?

I'm concerned because I just brought home 3 young panda cories and don't want to release them in the tank if it's something they might catch.

I've tried taking pictures, but he's pretty skiddish, so I can't get anything close up in focus.

HELP! :eek:
