I'd agree with your choices, Dragonii. I've kept guppies myself in a bowl when I was a kid. None of them ever died, and they kept making babies...

So they're really hardy fish. Same goes for mollies and Platies, both enjoy a tad cooler water than most tropicals, well, as you know

Danios on the other hand, yes, I've kept them too, Zebra Danios are good beginner fish, but I don't know... I don't feel like they're as forgiving as the aforementioned kinds.
