Just about 2 weeks ago we got 3 Platy from the pet store. One of them we picked because it looked much fatter than most of the others, assuming it might have babies. Well, I don't know if it's going to or not. It's belly is a lot larger than my others. Not by a whole lot, but you can tell. I got it one of those birth tanks for $9 just in case. I'm new to the Platy by the way. There are 3 out of our now 5 Platy who will go and sit on the bottom... and do nothing. The one I think to be pregnant is one of those.

The girl at the pet store told me how to tell male from female and I do believe it's a female.
But again, I'm new to this.

I read the average to birth is 3 weeks. I've had her for almost 2 now. What do I do?
