LIke the post above me says, I'd continue to watch it and keep an eye out for a RI. My boy het. albino has had one ever since I got him (about 2 months ago) and it's been a long battle because he was already in pretty deep when I got him, now I gotta get some antibiotics for him to assist in the battle. It's not too difficult to overcome when it's fresh but really it's best to avoid it all together.
It's something that snakes do every once in a while. They'll lift up part of their body and stare up in a trance like state.
