I have a guppy question?

I have had my 55 gallon guppy tank for going on 3 years now. I have about 6 or 7 of these bigger males that look nothing like my other guppies. I am wondering if they may be a guppy/molly hybrid, I have looked on Google and they to look somewhat like the pictures I found. I had 1 black molly male around a year ago in with all my guppies he was my last molly I have had nothing in the tank with them other than him since setting up my tank 3 years ago. They have all been produced in this tank I leave my fry in the tank with lots of hiding places and lots of java moss. Any help would be appreciated!!

to me that definitely looks like a hybrid. the shape of the head and size kinda give it away.

Yep, I'd say those are definitely Molly + Guppy hybrids in my opinion. I could be wrong, but they share pronounced traits of a Molly.
