Ive had my pixie since april and i purchased him a big size. Im guessing he may have been a few months old when i bought him. Anyway, ive noticed that he doesnt look much bigger since about 2 months ago. Do they stop growing at some point then have a growth spurt? Ive seen pictures of huge pixies and i wonder why mine hasnt really grown.

All i feed is nightcrawlers and occasionally pinkie. I do dust with calcium and vitamin so i just would like some insight as to why he hasnt grown.
