Awesome Molly/swordtail Pregnant Or Just Having Issues?

[generkon]

So I got this really cool reddish orange lyretail fish a few weeks ago, and I think it had had babies right before we got it. Anyway, yesterday it suddenly turned realllllly fat.

But this morning it was kind of back to normal size.

Does that mean it had fry last night? It's in a tank with four other mollies, two roselined sharks and some cories and amano shrimp, so they definitely could have been eaten, but there are a ton of plants so I can't believe they'd all be gone.... I really want fry!

Does anyone have advice on keeping fry alive or have some other kind of explanation, like a parasite or something?

She still looks pregnant in the 2nd photo to me.

In the first, she could just have been a bit bloated from feeding?
