Hi there.

Your BRB needs some space. At this size, I would personally get at least a 40 or 55 gallon tank. I'll let the experts chime in, there. Mine is two feet long, give or take, and is a baby, so he has a 20 long.

Humidity is crucial. I have a humidity gauge and I keep it high so far (all 24 hours! LOL) by misting the environment. I have moss in there for him, and the base substrate is Repti-Bark. He has a heat pad and a humid hide, and he has a water bowl large enough to soak in. I have covered the screen lid loosely with damp cloths. There is some condensation around the substrate at the bottom of the tank.

He has a branch he can wrap around on too, though he hasn't done so yet, and his hide is one he can climb on top of if he chooses.

You have a great new snake! Show us pics! They are so beautiful.

I am NOT an expert, but I just did a lot of reading and set my BRB up, and this is what I did. He seems happy so far
