I bought a Gray Tree Frog at the mall yesterday. How big does the tank need to be? He's in a 2.5 gallon right now. What kind of bedding should I use? I have newspaper down right now. Should I give him a bowl of water? I've been spraying him with a water bottle. Does he need something to climb on? I've put a rock in the tank with him.
That 2.5 gallon tank should only be very temporary. The gray tree frog will need a 10 gallon tank in order to be healthy and happy, 15 gallon tank if you want two. Coco fiber bedding is best, and use a low att bulb to provide mild heat for them. He will need a large saucer-like water dish to take a soak in.
In the ten gallon, he'll want more than a rock to climb on. Make it interesting, driftwood and other structures should provide interest while looking natural, for example.
Below is more care information than can be provided in one post.
