Is this normal

[Capt.jack]

I recently picked up a beautiful male Columbian red tail boa from a co worker, now I have heard that red tails are "escape artists" but mine is always looking for a way out. I want to know if its because I have a female dumerils boa in an enclosure next to him. If so should I put something up so they cannot see each other, or is it OK to have them in eyeshot of each other. I figured since they were 2 different sub-species that they might try to attack one another through the glass but my dumerils isn't really phased by him. Also my red tail has a bit of a temper, I do not know if its because the previous owner mishandled him or did not give him the attention he needed, but does anyone know any good tips for his aggression/defensive behavior?
