New Very Pregnant Platy

[boberga]

So on Sunday I bought 2 female guppies and 2 platies and I wanted to identify what kind of platy they are. Another thing about them Is that they a both at different stage . Pregnancy (same with t guppies) but this on seems like its going to have fry very soon and I'm not sure when to put her in the breeder box or if I should just let her be. These are the best pictures I could get at the moment. From what I see/believe, she is huge compared to the other female I bought and she is squared off. I will post pictures of the very pregnant guppy tomorrow morning as I post this right now before I go to sleep. Thanks

That is a very pregnant Pineapple Swordtail she looks like she is ready to drop very soon if she hasn't by the time you have read this! I would leave her be, a breeder box will stress her out, provide cover for the fry with floating plants if you can, if you only have small fish in the tank most should survive.
