Thanks for the advice Cheri. We have several ideas we are researching. Right now I think the front runners are D. Leucomelas and D. Auratus on the dart frog side, and Phyllomedusa tomopterna (tiger legged), or Red eyed tree frog on the tree frog side. We like that the dart frogs are active during the day, but culturing fruit flies to feed them seems a little daunting. On the tree frog side we like that fact that we can feed crickets, but the fact that they are nocturnal has drawbacks with the kids. We have decided to start building a vivarium first and get it established while we weigh our decision. Any suggestions on other frogs are welcome as well. We hope to turn this into a life long hobby for us, and a very nice science fair project for the kids. We plan on making the kids keep detailed records and help with every aspect from vivarium construction to everyday care.
