I mean how do you keep them and all their new babies from over crouding your tank? I remember my nanny having mollies that kept breeding and she just kept putting more and more in the tank till they started dying off. That just seems wrong ot me.
Im having to seperate my guppies in sexed tanks soon. You can also get a large-ish fish taht will eat the fry, like a betta (might be iffy with some fish) or a gourami (dwarf, probably). Since your kids are young, they wont really care much about the fish other tahn watching them every now and then, and saying good night to them! It'll be you and Dad enjoying them the most, so....what do YOU want? Flashy bright colors? A themed tank? A large school of one kind of fish? Get a few small cories for sure (pandas, pigmy, sometning that stays small), they are great little fish and compatable with most everything.
20 gallons is a GREAT starter size tank!!!
