Hello, My teenager and I have kept small freshwater aquariums for the last decade we began with a Betta when she was 3, when she was 6 we began with a 10 gallon and added a little tetra named Berry Blue, fortunately for us he was extremely hardy as we learned on the fly about water chemistry and over the years we have had a few tanks and numerous fish. My daughter is now 15 we recently lost our Berry blue :-( and added 3 guppies to our 20 gal. To our surprise they have begun having countless babies every few week with more on the way. We have put together another 10 gal for all the babies with spare stuff a 3 gal whisper with under gravel -t split on a 10 gal air pump and a old 5-10 gal submersible whisper with cut to fit floss in both for medium and unbleached coffee liners rubber banded to the intake. The babies are a joyful experience but any and all advise on how slow them down with little to no spending and to re-home the babies would be greatly appreciated.
