Are My Mollies Male Or Female?

Please look at the pictures attached and let me know if my mollies are male or female..

Both white and dalmatian are females. Is the left most picture the dalmatian one in the second picture? I'm only asking because in the first picture it's definitely a female, but in the second one the anal fin shape is a bit harder to distinguish.

It is easy to tell tropigod. The female has an anal fin, the one next to where they eliminate, that is a fan or triangle shape. The male's anal fin is modified to be basically a line shape and is used to impregnate the female. I don't have a clear picture of a male molly but this pair of pictures of a similar fish will let you see the difference.

Male

Female

The pictures are a bit grainy because the fish themselves are very small. They have a reputation for being the smallest livebearers of all but I don't know if that is true. As adults they are about 3/4 inch long for the male and about an inch for the female.
