Rainbow Boa Housing

[nock]

I currently house all of my Brazilian Rainbow Boas in homemade racks using appropriately sized Sterilite tubs. BRBs also do well in Boaphile cages, Vision cages, etc. The most important thing with any Rainbow Boa enclosure is limiting ventilation so the humidity in the cage isn't lost to the ambient air in the room.

So they don't need the height space like an arboreal snake? And does the rule length + width of enclosure > length of snake apply?
