Have a 4x2x3 cage empty now i think its an neodosha, i had my argentine tegu in there for awhile before i got rid of him now its just sitting there and don't know what to put in there now, any ideas no snakes.
I'm going to have to disagree with anyone who said your cage would be appropriate for a monitor. The only monitor small enough to live in a 4 x 2 footprint is an ackie and they need at least 12" of dirt or other substrate that will hold a burrow. I don't think that neodasha makes a cage capable of holding substrate that deep without modifications.
If you're looking for a larger animal and trying to avoid some of the more "common" species, my suggestions would include a blue tongue skink, a smaller tortoise like one of the testudos, or a couple of the larger species of gecko like leachies.
