So... When Will I Be Able To Sex Them?

[Amunet]

I know I asked this before, but I'm not seeing any change in any of the platy fry genders.
They all still look female to me.
I think it's been... hmm.. almost 2 months now since they've been born? I can't remember... but it's been a while.
Some of the fry are almost just as large as the little female momma.

When should I be able to sex them?

Just before threee months usually.

 

[helterskelter]

it's around 3 months you see the first sexing out, but some late developers can take up to 8 months to mature

On that note, when do they grow little swords?? (sorry to hijack the thread, but I've been wondering...)

 

[Colin_T]

6months onwards before the sword part appears. And it can take another 6 months to reach full size.

The males gonopodium develops after a month, with the fry being so small it can be hard to tell still, usually at 8-12 weeks it becomes pretty easy to see

You may get an odd promiscuous male develop early but not all males, Platies take a while for the gonopodium to start to develop as said before 3 months or so to be sure.

 

[Amunet]

Looking at them closely... some look like they're developing the male part, but of course it's still hard to tell whcih is why I asked this lol.
So anywho, thanks everyone! Guess I'll have to be a bit more patient

The bottom edge of the anal fin on young males starts when thicken they start to develop a gonopodium.
