You can set them up like pretty much any other tree frog. They do not need to hibernate, so you can use tropical plants and keep them indoors year round. I would not advise bringing in soil from outside, it is not likely to harm the PCF but it would increase the risk of cross-contamination to your other frogs. I keep my group in an 18 x 18 x 24 Exo Terra, at a minimum I would recommend a 20 gallon aquarium or 18 x 18 x 18 Exo/Zoo med terrarium. If you are interested I could also give you a quote for a custom terrarium at whatever size you want, just shoot me a PM.
