You guys said it all pretty much but as far as aspen goes I love it and have no problems with humidity. If you do get a big tank just remember to crowd that thing up with plants, vines, your 2 hides and as much as you can do to fill all the empty space until your bp gets bigger to make your bp feel secure throughout the tank and not feel exposed. Just think rain forest and don't stop till it looks like one...lol.
