thank you for your help
I am not trying to upset anybody, and i love animals and would never want to be cruel to any, but there is no chance my mom will let me get a tank that big while the frog is small, so I think I will start with the 18x18x24, and when he gets bigger I will get a larger tank if somebody could link me to an article or thread on substrate choices and water containers then that would be super fabulous!! hopefully I'll have a frog to post pictures of very soon! I will be getting a blue dumpy tree frog
