The Whites tree frog is a very good choice. There are many members here who keep them. Have you had a chance to go through the photo gallery? Look at vertically oriented tanks with a lot of branches and large leafed plants. They are a large tree frog so stay away from delicate plants. They like to perch up high so give them as many places that they can climb to as you can. Purchase a captive bred frog only from a reputable breeder. Avoid the big box chain pet stores. By doing this you may have to pay a little more for the frog but you're more likely to start off with a healthy frog which will save you a lot of heart ache and money in treating a sick frog. Let us know when you get one and post pictures. Welcome to the addiction.
