lizard for a 36Lx18Dx18H exoterra

I will be moving my beardie out of his 36Lx18Dx18H exoterra and wondering if anyone has any ideas of what to put into the terrarium. I was thinking of a leopard gecko but wanted to see if anyone had another ideas.

Are you sticking with lizards? Or open to other reptiles/amphibians?

I was thinking lizard but Im open to other ideas

Fat tailed gecko, crock skink, fire skink, or you could make a pretty cook viv for some frogs...
