Mine eats crickets, but they can probably eat various invertebrates, such as small locust - something that crawls around and jumps. Every now and then (like once a week/every other week) I dust them with tree frog dust (similar to ReptiCal but specially made for tree frogs) by T-Rex. I've found it's getting hard to find this (at least where I shop) - but I've seen they sell it on Amazon.com. A jungle/tropical type of setup would probably do them best, with lots of plants and branches and such for them to hop around and climb on. Mine loves to explore and will get into the strangest places - like behind my 'rock' wall background I have in the cage. I made it so she can't do this anymore. Mine is housed in a standard 20 gal tank with two other frogs and she seems content in it. If you don't have a tank already, a tall one would probably work well so there's lots of climbing room. They like their temperatures to be somewhere around 77 and 86 degrees F. So room temperature (in the 70's) is just fine. If your house gets colder than that, or in the future (such as during the winter) you might consider putting a heat pad under one side of the tank - but make sure it's only on half to 1/3 of the tank, so that they have a cooler area to go to if they get too warm (unless you have a tall cage where they can climb up the walls). And don't put it under their water dish. It will also need a shallow dish of water for it to sit in and soak and a small hide for it to hide in. Make sure you have a good screen top and that it shuts securely - these little fellas like to try and escape! They can be very active and jumpy and mine's been known to jump distances of like 4-5 feet! They don't need any special lighting. If you want to have a light on the cage, you can use a standard aquarium/terrarium florescent light.
