Beautiful Sunglow! Mazel Tov! Great contrast and I am sure the pictures don't do him justice!
Is he a 2018 baby? How much does he weigh? He looks tiny!
His mother looks beautiful as well. I am by no means an expert, but from what I have seen, the mom looks Sunglow to me. As you said, the Sunglows tend to hold their color better than other albinos.
Behira, my female Ghost BCI, just turned two years old (she was a June 2016 baby) and is a good 950G. She was 440G when I got her at just over a year. They grow fast, but have a LOT of growing to do.
She's a sweetheart and will be a gentle giant ((she has become my favorite snake - SHHHHHH - don't tell Shayna (BP), Figment (adult corn), or Solana (tiny baby corn)). How's the temperament on your little guy?
Good luck and keep us up to date on his growth!
P.S. I just re-read the post and it seems this is your first BCI. I am still new to BCI's with Behira being my first. However, I've learned a lot, and there are quite a few Boa experts on here, some of whom have already posted (RichardHind1972). Ask as many questions as you have or want answered! We have a good group of Boa peeps on here who will chime in.
