I have bred timor's, argus ,argusxflavi and blue tree's. I think a timor is more what your looking for. My next suggestion would be the ackie. as for a hide. There are alot of things you can do. So just use your imagination. A box with dirt is good. As for timor monitors they seem to like a hide box with lots of dead leaves they can burrow under.(shredded paper works just as well and is a lot easier to deal with) for ackies,argus,flavi's ect... I prefer a sand substrate, build it up on one side (just a little) then place a large diameter piece of Pvc on top (angle it slightly so the entrance will be elevated) and then cover the pipe except the opening with more sand to make a mound with a hole/cave.) I usually keep the undertank heater under the mound so the heat stays pretty high in the cave. and on the other end of the tank the sand should level out and have a water dish large enough for soaking. (they do this alot) I usually keep a flat piece of rock as a ramp up to the top of the water container and use a heat lamp over that end. Make sure to change water and clean container daily. they love to purge while in the water if you know what I mean.
