Baby Platys Question

[newhobby]

Hi,

Today i noticed that I have about 7 or so baby platys in my aquarium. If they are about half a inch or so, maybe a bit less, how old do you think they are. I know this is a silly question, but i'm only asking because it was so totally unexpected to see them.

The biggest of my one month old platy fry is about half an inch or so. But it was fed regularly and was ensured at the least 3 meals a day.
