Some may stay low but that's not all the time. I have three adults in one viv (yes, I know - we won't start that debate) which is the equivalent of a 260 gallon aquarium and they have plants and vines and most of the time they're off of the ground - either on the plant pot, in the plant, or on the vines higher up. I've seen them climb to the very top which is 6' off the ground. Although they don't need the height (I have another that is in a flat viv) I think it's fun to watch them climb. If you're going with an aquarium I wouldn't worry about it. Just my .02DaemoNox said:Hight really isnt too important as they are more terrestrial animals (evident by their body shape). Occasionally they will do a bit of climbing, but dont be suprised if they stay down low most of the time, especially as adults.
