Sexing Molly Fry

[Flunter]

Howdo all
My Sailfin Molly gave birth 6 weeks ago and I managed to rescue 8 fry. They have been surviving well in a seperate 6.5 gallon tank.
At what stage should I successfully be able to sex them?
At the moment, using the round anal fin for females and pointed for males method, all 8 seem to female

if there nebrons you cat tell but after 1-3 weeks you will see a poited anal fin or a rounded anal fin.

Perhaps they are all female? Be patient and watch them closely, if ones a male, wont be long til he starts humping all the rest!

Males generally have the rounded anal fin and appearance of a female for a bit, then develop a gonopodium. If you look closely, you may notice some anal fins are a little more pointy. Most males will have clear gonopodiums by 3 months, but some can also be late developers. You have to keep an eye out for a while!
