Sexing Baby Mollys

[stucolls]

Hey ervyone, I have just released my 2 remaining dalmation molly fry, Hercules and Zeus, into my main tank to live alongside, 3 female dalmation molly, 4 mixed platy and 3 peppered corys.
They are just about the right size to go it alone now, and seem ok atm.
My question is when can you sex them? they both at the moment, appear to have fan like anal fins (suggesting female) but could thi turn into a gonopodium and if so what kind of age? they are exactly 15 days old today.
I was hoping for a little boy to replace my only male who died yesterday.

Thanks all

Stu

it can take 4-6 months with mollies to develop a gonopodium and if you have a very agressive male it can supress then for upto 10 months to allow then to grow to a large size.
