I have a female Dalmatian Molly with the Lyretail colored like yours, except it is a balloon belly one, not the streamlined shape. But she did have babies, so I am hoping there are some nice Dalmatian Mollies in there to grow up to be beautiful. I know there are several by the color & they have the normal shape, just hope they don't turn into balloon bellies, too.
I now know the balloon bellies are hybrids, and at first I thought they couldn't have babies, but 3 of them have. One, the first I bought because it looked like she was about to pop, fooled me, and after a month and half I started checking and found out it is a Male, balloon belly. The female really big balloon belly hasn't had any babies at all, but she is the head lady fish -- an aggressive alpha female. Very unusual color and shape, but no babies which is unusual.
Having gotten the big second batch, there are 2 gorgeous males -- one is a 3" iridescent, yellow head sailfin lyretail Molly (which I am told is called a green one?) that I am trying to get a pix of. When I do, I will post it. He is a big boy, and flits about like a leader, but he isn't. The leader is an orange sailfin Molly, who will knock your socks off he is so aggressive. He will breed with anything that is in the tank, and chases all of the fish constantly.
