However i think you might want to try Danios. i had kept four danios in a five gallon tank for a year. A five gallon is so small! i didnt have any heating and they were fine. They are quite hardy and you wont any baby problems
although i must add that everyone has there own opinions about the fish that can go in a five gallon tank. Maybe guppies also.
Yeah, my opinion is way different. While they may be "hardy" and capable of surviving, Danios are very active and should have plenty of swim room. I have some in my 10 gallon QT right now, and IMO...they even seem cramped in there.
