Help Indentify

[teganoid]

I have two small bright pink freshwater fish with three very thin white lines. I'm not sure what they are, but one of them is looking rather fat lately and I'm afraid she's pregnant & I have no idea how to handle babies especially if I don't know what kind of fish they are.
Can anyone help?

It's the one above the swordtail and in front of the rock. I took this picture when I first got them so I'm not sure of the sex of either of them or whether this particular one is male or female.
Please help me.

Welcome to the site

It's a glofish (neon danio). More info here: GloFish® Welcome

Danios lay eggs, so she isn't pregnant. If you've got a male in there (he'll be thinner than the female(s)), she'll lay eggs occasionally and everything in there including the parents will have an extra lunch that day. So you don't need to worry about raising babies. You probably won't ever see any eggs, being as they're teeny tiny and everyone eats them anyways.
