I will be breeding guppies soon. I am open to advice, also, will I need one if those breeder systems whee the mother that is pregnant is in one area, and when the babies are born, if they are live bearers they swim down through a crack in the bottom that the mother can't get through, if they are eggs then they sink through the crack so the mother or parents can't eat them. Will I need one? I will have a ten gallon as my main tank for the adult guppies. to start, I will put a breeding pair in my just done cycling five gallon. Then, once the mother is pregnant, I will move her to either the breeder system I asked if I needed, or I can just manually move the fry to the five gallon and let them be without any adults. Any advice? Also, I need some good breeding pairs... especially females. Anyone have any?
