What should I put in my new 12x12x18 Exo-Terra?

Possibly a small day gecko species, but it is just so small. I would go for something larger for long term housing for any animal, at least if you go for an arboreal lizard or frog, the tank will make most of its size in height and not take up much more space in the house. One of the problems with such small tanks is providing or maintaining thermal gradients and UV gradients, whilst still offering enough space for activity without them being pinning them under heat or light all the time
