can you remember roughly how small he was when you got him? id hazard a guess at around 10-12months but he could be older,
tbh guessing age from length isnt very accurate.. i have a 4month old corn who is coming in at about 17-18inches long but then my non feeder who is just over 1month old is already pushing 15inches.. If your snake was fed on a shop diet - when they are only fed once a week so they can stay in smaller fauns/vivs for longer - then it could have drastically affected how much he will have grown when he was younger..

3 pinkeys he was about 10 inches when i got him and was the size around of a pen and yeah before i got him he was on a shop diet but my friend who worked there said they only got the one i bought in about two weeks and you cant see the rings for all the blood just a tip :)
really if hes on three pinkies a time he should be on small fuzzies.. try him with a fuzzy next time and then gradually work up to two fuzzies and then the next size up from there

when one fuzzy leaves a very small visible bump once it has moved down to the thickest part.. if hes on 3 pinkies he should be fine - probably just not used to having the equivalent all in one go thats all
