Sexing Lyre Tail Mollies! Need Help!

[jordan1231]

I have a dalmatian Lyre Tail mollie that I originally thought to be male but upon close examination I mistook the long skinny front fins to be the gonodolium. It has the triangular back fin and the two front ones are long and skinny. If I am correct it needs to be the BACK fins that are long and skinny for it to be a male right??? ALso it does have the forked tail. Is that a male and female lyre tail characteristic??
Thanks

It's the anal fin that has to be long and skinny. I would trust to that rather than to any characteristic of the tail.
