Snake Expansion

[Chris WT]

I'm looking at expanding my snake collection this October at NARBC. I'm looking to pick up 1-3 colubrids of various species all from the same region, my question is could I move my boa into a rack system with other snakes? I understand I need to pay special attention for humidity but other than that the temps are about the same.
This is really a space issue and a Boaphile "Ball Room Rack" seems like my ticket.

In fact reading on about that rack system it has 2 rows of flex watt that can be controlled independly. So tropical stuff at the top and temperate at the bottom. Is this unethical or wrong?
