we have a 20gal long tank with nothing to do with it... i would like to put something in our childrens room for them. what would be a good pet that could be observed (The balls are pretty shy, especially when the kids are around) by looking in the tank? preferably something i could keep warm with an UTH so there is one less thing to pull/fall over. We do already have lamps (uvb & heat) so if needed we have them. I would like to get its enclosure set up and the tank placed in their room several days before we would bring something home.. i was thinking maybe a tortouise (Sp?) or geakos?? something that isnt too horribly difficult to keep alive would be great lol, we had a horrible experience with our last reptile supplier so we wont be going back there... bearded dragons are cool but seem difficult to maintain... any suggestions for a first timer? weve had a pair of veiled cameleons, they were awesome "google and leid" sadly passed away when we moved, they never did grow much come to think of it.

thanks in advance
