Sexxing my Lyretail Molly

[Kelseyghardin125]

Hello again! Can someone identify if this is male or female lyretail creamsicle Molly? I have a make Dalmatian Molly in my tank also and know that the Dalmatian Molly is a male. He constantly is chasing my lyretail and rubbing his nose on the lyretail’s belly like an attempt to mate or something. Which makes me think that my lyretail may be a female but it’s so colorful and bright (and has what I believe is it’s gonopodium but that could just be how a lyretail’s fins look?) but it makes me think it’s a male? Also, I’ve heard from an uncredited source that lyretails are sterile? Is this true? Thanks so much for any and all responses! I’ve added a few pictures of my lyretail

I'd assume it's a male due to the fin markings but do not take my word for it, I don't house mollies I mainly breed Endlers and guppies.
