Hello, you will love keeping brevis. They are one of my very favourite critters. Mine are very active through the warmer months and will go about their business while you sit in front of them watching their antics. Even feeding from your hand. They are very comical little buggers, strutting around like a big old lacie or snoozing in a corner like they are sitting up in an arm chair and stuff like that.
I've been trying a couple of different things with them and keeping more of a tab on events this year and was planning a thread on it all once the season is done but basically you'll want a basking spot at least in the fifties and up to even the high sixties. The ambient temp is also important, a minimum of around forty through the day in the breeding season will keep them active. Being a small animal in these temps they need access to a humid (but not wet) piece of burrowing substrate so they don't dehydrate. I've seen them drink from a water bowl - which they take great pleasure in filling full of sand as soon as you change.
I have a few clutches incubating and a few more yet to come by the look of things - touch wood.
I've had clutches ranging from two eggs in their first season up to five at adult size.
Anyhow I'm no great authority and this is just how I do things but have had some success with them for a few years now. Hope I was of some help.
