For my next reptile purchase, I'm thinking of getting an Eastern Water Skink and a Perons Tree Frog, and having them live together in a very large fish tank, that includes a small fish pond and lots of plants. I'm think that I'd need to get a 4ft aquarium, have the first foot as a pool area with some feeder fish, then the rest as habitat with lots of ground shelter and branches. Would those two species live together well? What sort of maintenance would a set-up like that require? Any other advice or warnings?
