My brother just called, and mentioned this,so I don't have a lot of details. Thought it could possibly be a common thing and y'all could answer without much detail.
He has a molly...who has been sick but has been moved back to the "home" tank. She had those yucky parasite worms. Anyway, now she is developing some black spots. He says it just looks like a pigment change or something. They aren't raised or anything.
Just curious if anyone had any ideas. Not seeing it, I know it's a difficult call, but I decided it can't hurt to ask!
