Thank you very much first of all...i try to learn all i can off the internet, but i havent learned enough obviously. I am getting 2 new tanks to seperate them into groups and wondered, how i should seperate them, im guessing by zones but i have more than 3 zones as Kurt has pointed out. And im not sure what the brown tree frog is either I got her at a very poorly kept reptile store with no title to her, and she was the only one. she has stripes sometimes and turns all colors of brown with a fairlypointy nose,big eyes, and jumps so fast you cant see her.
