thanks for the responses, I guess what I was looking for was if they had the same requirments as far as their environments. Also if they would stress each other out. The reason I was asking I want a second white lipped, but can not find one and I came across the vietnamese blue tree frog. Any way I guess I need a bigger Terrarium. From what I have read a 30 gallon tank would be big enough for two WLTF, and my volume works out to a little over 30 gallons. What size would you guys recomend for two WLTF?
