see even Kathy doens't have one answer, yes do it, no dont. it's up to you, just take the proper precausions, feeding, time after feeding apart, ect.
keep them apart for 4-6 hours after feeding if you feed them on different days, if you feed them back to back, then a half hour is fine, but I keep mine apart for a few hours anyway, just to be safe. I am getting a 40 gallon breeder for my two, they are females, not breeding them, obviously, but that is a fine size, a 30 should be ok, depending on what size they are, I will probably, or maybe not, seperate mine when they are full size. and put a different snake in the 40 gallon breeder, a bigger snake.
