How to tell male from female platys?

[papa_bear_21]

We have a few mickey mouse platys, and are trying to figure out which ones are male and which ones are female. How does one tell, what do we look for?

Thanks in advance

Click on the link and it will explain. But short simple version, is the anal fin of a female is fan shaped, a male is straighter.
