No one has replied to this so I'll have a shot, even though my experience is limited.

I had a rosy boa for a couple of years around 20 years ago. She was around 13 years old and less than 3 feet long when I got her from the original owner, and he had raised her from a baby. She was no trouble to keep in a setup similar to a similar-sized corn snake -- 10-gallon aquarium, under-tank heater, newspaper substrate, water bowl, hiding box and a rock to help shed on. Heat was turned off at night, and cage temperature fell to room temperature. I do not recall giving her a humid hide at shedding time, and I did not remove the water bowl at any time. As for substrates, anything acceptable for corn snakes should also do for a rosy boa.

The little boa was a bit timid. IMO, she benefited from the hiding box. While she was not a particularly aggressive feeder, feeding response was acceptable, about equal to an eastern milk snake's feeding response. I gave her dead mice that had cooled to room temperature but had not been frozen. So I cannot comment on how easily a rosy boa would convert to f/t.

I did a web search for rosy boa care sheets. I looked at this link (http://www.reptilesmagazine.com/Care...oa-Care-Sheet/) and it looked good to me. There are other care sheets that I did not look at.

By the way, be sure to check with your state fish and wildlife department (or Department of Natural Resources or whatever it calls itself) to be sure that it is legal for you to keep a rosy boa. That may be the biggest stumbling block.

Good luck.
