It's never a good idea to house two snakes together unless you REALLY know the snakes well and are VERY experienced in caring for them.
BPs need very little space, even as adults. Floor space is always more important than height, and a good enclosure should be about 12" high, and no taller than 18".
Even the largest adult females can be comfy and happy in a home about 36"Lx24"Wx12"H.
But, by all means, show some pictures of the Redtail enclosure!![]()
