So i have a spare 29 gallon tank that i used for my beardie (it has the same dimensions of a 20, just taller) and i was wondering what could go in it. Any suggestions? I would be open to almost anything, as long as it is not too expensive. What types of lizards or snakes would YOU put in it if YOU had it available? By the way, it was designed to hold water but doesn't anymore, otherwise i would have put some piranhas in it long ago. Thanks for ideas!
