What is the gender of my Dalmatian lyre tail balloon molly?

So I have a 20 gallon tank I will be putting a new Dalmatian Molly into but was wondering what is the gender of the fish?

I’m going to go with male as it has only one rear fin where as females have two if you could provide a few pictures of it’s finnage I could tell for sure ps hope this helped

It's a male.

Male livebearers (guppies, mollies, swordtails & platies) have a long straight anal (bottom) fin called a gonopodium.
Female livebearers have a fan or triangular shaped anal fin.

Young males have a fan or triangular shaped anal fin too but as they become sexually mature it changes into the gonopodium.
