My bearded dragon has finally out grown his 20 gallon long aquarium and i'm gonna get him a 40 gallon long. I was planning on moving my leopard gecko from a 15 gallon to the 20 gallon, and that leaves a 15 gallon empty, and we can't have that now can we?:biggrin: So what gecko(s) could comfortably live in a 15 gallon?
