Housing in the same rack?

Boas and pythons shouldn't mix, I know. I've heard so much about the fears of IBD and other bad outcomes of keeping say, a RTB and a ball python in the same room/rack system. I just never hear anything about colubrids and pythons in a room together, or colubrids and boas in a room together (after QT, obviously).

Would this also be a horrible idea?

Would keeping, say, a milksnake in the same rack as a ball python (after a good 3-4 months or more of qt) be a bad idea?

If they've been properly quarantined, I don't see any issues with it. Just make sure that the species all have the same temperature requirements.

As long as everything is got a clean health your perfectly fine.

I kept kings and corns in same room at balls. Only gave them room temp with no hot spot since it is 82 in this room.

Boas i kept at 80cool 89 warm for established ones and 93 for babies

My Milk Snake lives in the tub next to my Cinnamon BP with no problems. :)
