Breeding

[kiashasw]

I just purchased some Glofish Zebra Danios, I noticed that one of my fish's stomach has been looking a litter fatter so I assumed this fish is a female. So my question is how do I get my fish to breed should I move her and the mate to a new tank. I should include that the other day I saw a fish chasing her and I assume that was the mating ritual but that was a week ago and I haven't seen any eggs or babies but her stomach is still big. Any comments, advice, or anything will help. (I'm new to the hobby so I don't know much).
