in a couple of weeks my little guy is getting a great big new habitat, so I'm toying with the idea of a new herp to fill the smaller cage.

any suggestions on something friendly that won't outgrow a 30x12 tank?

right now i have a male uro who i absolutely love. i can't think of anything similar that can comfortably live in a smaller tank. low maintanance and non-meat eating is preferrable, i'm also open to non-lizard suggestions.
