I don't have much experience with red tails, but my some of my family does. The only thing they've told me is that they are temper-mental(then again I guess that's any boa maybe? My rosy boa is somewhat temper mental.) And the aggression during and after being fed. My sister had one at one time- I swear she's traumatized over it. It was super aggressive to where she wouldn't take care of it and had her boyfriend at the time feed it. She won't even go NEAR my tiny boa. Anyways, just depends on the snake to me. You may have to work with 'em a bit, and if it were me i'd at least take him in *quarantine* at least til you can find him a home.

Then again, I don't have much experience with boas, so if anything I have said is wrong don't hold me against it please.
