Figure about a 60-70 gal. tank size with screen top...you want good ventilation. These are day-time active hunters, they happily take f/t rodents, and especially
when hatchlings, can be pretty feisty. Most out-grow that, but personality is partly genetic, & a big part experience/learning. I've kept, bred & raised both bull &
gopher snakes...the only downside would be they can be restless in too small of a cage...as I said, these are ACTIVE hunters, not ambush predators like BPs. The
temps. needed are pretty much room temperature (70*) for most of cage with UTH (about 85*) at one end for digestion. All of mine were tame to handle easily once
grown, & they 'change gears' pretty well too (ie. they were smart enough not to think I was edible if I handled them after a meal).
