Yellow coloured B. Schlegelii have gained to himself a few (white)pale scales. (Those is seeing at the center of photo). Snake is born 2005, eats and does moulting (renew his skin?) like he should and he behaves normally, pondering snakestuff all day long. Is this colour changing thing normal? Maybe related to age? Only few scales are getting whiter, there is no signs of infections or other skinproblems. If you know some other site/forum/expert where I can ask about this, I would appreciate that info very much.
