What disease does my molly have?

anya

I cannot seem to find any information on what's wrong with my marble molly. She has just given birth a couple day ago and both the fry and the mommy seemed perfectly fine. Today I noticed that her lower lip is red and swollen. She doesn't seem to be bothered by it, at least there's no behavioral changes.

Anybody knows what this could be?

If you have any pictures of the swollen lip, they could help in diagnosing the problem. However, the swollen lip is likely to be a flesh wound from fending off other fish from attacking her young.
