Hello Jess! Don't keep Rana; but here is a care article for the Leopard frog: Frog Forum - Leopard Frog Care - Rana pipiens (Schreber, 1782) and R. sphenocephala (1886). The explanation on care and habitat pretty much applies to the Green (AKA Bronze) frog. There is good info here on the Green frog natural habitat: AmphibiaWeb - Rana clamitans.

IRT getting frogs, you can post a note with your needs at the "Wanted" forum section and hopefully someone can get you frogs or tadpoles of desired species. Good luck !
