How many gallons of water does 2 guppies need to survive?

Answer 1

Well, 4 guppies would be fine in a 2 gallon bowl, but they breed a lot, so you'll have to put them in a 10 gallon tank once there is fry [put the fry in the 10 gallon tank, not the parents!]. But if your just keeping 4 females, or 4 males, they can live in the bowl just fine. I would not put them in a 1 gallon, or 0.5 gallon bowl, though. It's not big enough [not as big as a 2 gallon bowl is]. You can feed guppies betta pellets, betta flakes, or even a broken goldfish flake, if your guessing what to feed them. If you just had goldfish, or betta fish that just passed away, use their fish food to feed your guppies. It won't hurt them, because guppies can and will eat just about anything you float on their water.

Hope this helps.
