Thanks for all the kind words everyone!
Wallace is 2 and a half years old. He turns 3 June 1st.
He handles fairly well but does have a "flighty/twitchy" side.
He's only bitten me once and that was at an early age. The second time I thought he bit me was not a bite. I actually snagged my hand on his teeth when he was backing out of my hand.
If he grows more, I'm hoping it is not more than a foot maybe 2.
He's a good captive, but the boa and carpet are more relaxing to handle.
That said I'm happy I have Wallace!
