How pregnant is my platy

[Preggoplaty]

I'm assuming it's pregnant and not really fat I just need to know when to move it to the box thing I've never had breeding fish before so I know nothing pretty much thanks

She looks like she has a while to go yet, but she could just be young; young females don't get as big as mature females.

We don't advise the use of breeding boxes. they're too small for the mother to feel comfortable, and too small for the fry to grow properly. Add lots of live plants to the main tank, if you want some fry to survive. Bear in mind that each female can have 25 or 40 (sometimes even more), every 30 days or so, so that's a lot of fry. The fry don't need any special care; just clean water and food, which they can pick off the live plants when they're very small, so that's another good reason to have some.

If you want to raise more fry than that, you really need a second tank, at least ten gallons, that's filtered and heated and has a cycled filter.
