like Homegrownscales said room temps are good for crested. mine jumped ran under the fridge. i was afraid to get bit and let her run under the fridge... luckily i had my friend over and we dumped the fridge and lifted it. i was afraid of rolling it over her. my suggestion just keep looking and risk the bite it will save you the head ache of chasing it again.
good luck u will find it!!!!!
