Well, I'll recommend you make it with two seperate enclosures. BP's aren't a social animal that lives in packs, and pretty much the only reason to keep them together is for breeding a few months of the year.


With two seperate ones, if they are on the same level, I would say put the heat tape on the bottom, right in the middle where the two cages are seperated, so that either far end for each cage is the "cool side", and where they are connected is the hot spot.
