Cute boa, looks like a nice light normal Bi (was BCi), probably from a light/high pink/pastel type line. No way to know without the history of the parents. I'm not seeing any morphs though.
Good luck with the mites, they can be a pain.
no, not at all.
It takes a while to get the hang of it, but look at lots of photos side by side of the diff types and descriptions, it'll start to get easier to tell over time.
