I'd keep an eye on those babies... For all you know, the babies are platy-molly or platy-guppy hybrids, which I'll bet would be interested.
I hate hearing people say "it's only a $3/$5/$1 fish/shrimp, so it's ok if it dies, I can just get another." It's still an animal! All animals should be treated like they're worth $10,000.
