Hi. I just got a corner 30gal tank that I want to make a terrarium out of for dart frogs. The only thing Im still pondering about is what kind of bottom to use, layered or false. I have a book on dart frogs and they say that the false bottom is the best choice in all cases. However after reading the forums most people say that false bottoms are only appropriate for terrariums with water features. Can someone clear this up for me?
