I have been breeding guppies for over 30 years for fun. You do get alot of fish, but pick the nice ones u like and give the other ones away when they get bigger. I bring mine back to the pet store and trade for supplies. I donot take it to a level of perfection, just fun..... Live plants and guppies are the way to go. I would not mix guppies with other fish except for cat fish. Other fish like tetras would pick on them and chew there tails. Just my opinion on guppies.
