when will i be able to tell the sex of my fry

[daydreams_uk]

My molly fry are 2 months old now (born Mar 23)
They still all appear to be females.
When does the gonopodium start to develop?

They should start to develop after 3 months mine did anyway

when they are about 1 inch long or about 2 r 3 months!

Some of my mollies were born very mature and I could tell the sex within a couple weeks. Generally, though, I find that I can tell the sex when they reach an inch long. If they are still tiny, feed them small amounts, but often. Fry have a voracious appetite, and if fed properly, will grow fast. Good luck!

My fry are all different sizes even though they were born on the same day
the largest ones are around an inch long (including tails) is it when the body alone is around an inch?
