Is my male guppie trying to breed with my mollie??

Question

I have 2 male guppies and 2 mollies in my 20 gallon tank.

1 of My male guppie is ALWAYS following 1 of my mollies, and every time the mollie is still, the gupppie starts making some weird poses and trys to breed with the mollie (I think).

But now that mollie has a bigger belly than the other molie.

Is it possible that my mollie is pregnant with the guppies babys?? Or is this something else? Should I remove that guppie?

Answer 1

a guppie cant mate with a molly. if its chasing it check your water conditions like pH and nitrate. if theyre all ok sperate the mollie and see if shell release eggs.

Answer 2

that means that there trying to hit him my male guppies use to do that with my female betta and the next day i seen them fighting and the guppies won
