The monitor is maybe 5" long or so so he is still a baby.

Mumps and Mettle, how do you figure that no reptiles should be kept in tubs? I'm pretty sure that MANY people use tubs for their snakes (if i'm not mistaken that is a reptile) along with me using a tub. I am looking to give him more than he has so instead of being so negative why not give me useful suggestions and if you are gonna flat out say it won't work then give me reasons why it won't because if I am not mistaken, a heavy duty sterilite tub will hold a crapload of dirt anyways.
