Help! What is this on my mollie??

Hard to tell from the photo but is it a female? It could be a gravid spot?

Looks like a gravid spot to me too.
Any chance of more photos please? This is very blurry for one thing, makes it hard to be definitive.

I agree that it is a gravid spot

here is a photo of a gravid spot with a molly very similar to yours
