Breeding Mollys

Question
How do you tell the difference between male and female Molly's?

Answer
Hi Brian;

Look at the bottom back fin. In the male it's pointed and on the female it's fanned out and sort of crescent shaped. Here is a web page with images  of a male and female platy to see the difference (the male is on the left). It's the same in mollies;
