Mollys fighting or mating?

[Sharptank]

Does anyone have a clue as to why my Dalmatian Molly fish (speckled) is chasing my Black Molly around like this and flashing his dorsal fin in her face? I believe the speckled Molly is a male and the Black Molly is a female…. Could be wrong. Any thoughts?

Yep They are probably trying to mate.

Hi and welcome to the forum

The male is harassing females and trying to breed with them. Stick him in his own tank for a week to give the girls a break.

thank you! I might have to set up a separate tank for her. I have 2 females and 2 males. She looks like she’s pregnant?. We feed them in the evening time, her belly shouldn’t be this full.

Try not to move gravid (pregnant) female livebearers because you can stress the females or injure the unborn babies. If you need to move a fish out, move the males.

Have lots of plants for the female to hide in when in labour and for the babies to hide in.
