Thanks. The sunglows are, in my opinion, one of the nicest looking boa morphs out there. I think yours is a pastel. It looks like a normal Colombian, except for the pinks down its sides. I do not own any pastels, so I do not have anything to compare it with. I bet it will darken somewhat, and get better looking with age.
That's pretty funny about the boas flicking their tongues at you. That is just their way of sensing you.
