I don't want to sound like a jerk, or start trouble. It's incredible how much interaction my snakes have with their decorated habitat. I understand they thrive just as well in racks, but it amazes me how many people feel they can't do well in a properly kept aquarium. (I kept over a dozen boas in the nineties in a more of a rack type set up, and now have balls in decorated tanks).And how they truly can be to an extent, a display type animal. That said suction cups, but they do get knocked down every once in a while.
