had this fella for about 1 year now, and would like your opinions as to what he could be...

he permenantly has a 'matt' appearance (doesnt shine like any of my others)
blushing on his spine is 'fusing' with the dorsal pattern ,creating an almost stripe as he gets older, was dot-dash when he was young (over 700gr now)

btw, he shed about 1 week ago

apologies if the photo's are large, could a mod please re-size - thanks
