I have several snakes (as pets) and about 2 million asian house geckos (wild). I always get an array of green tree frogs and hundreds of other assorted frogs. But alas, i also get too many toads

Maybe I can put a toad in there haha... It's certainly not illegal to keep them as pets, it's just illegal to ship them out of state.

I was thinking of scorpions actually. My girlfriend did elude to the fact it would look cool with a scorp in there.

But I was not to sure if it would be able to escape easily. As it doesn't have far to climb that's for sure and I don't think I can provide the right temperature/humidity.

So far the temperatures range from 20'C (first thing in the morning) to 34'C around 7pm at night (when lights go out).

The large gap (no lid) between the soil and the light lets all the humidity out. The soil heating also prevents water from condensing on the cooler glass. Plus the desert like conditions.

They were given a splash of water (enough to wet thr top few cm of soil around the cacti only) last night, and that's nearly all evaporated now. Condensation after nearly a week is still nil. So - the experiment continues.
