Okay, so tonight I am planning on cleaning out my old lizard cage. I have been thinking about getting either a crestie or a leo, but I'm not sure which I want. I currently have a 12x12x12 Exo-Terra cage. Would this be a better size for a crestie or leo? I'm not sure how many gallons it holds. Also, would a mini sized UTH be suitable? Finally, it came with a foam thingy to stick in the back for a lizard to climb on. Would this be necessary to clean and how would you do it? Would I be better off just throwing the foam out? Thanks! Oh yeah, and which type of gecko would be better suited to live in there? It would most likely be a juvenile or a baby.
