When I got Enchantress she was 40 grams (that was in August) she is now 88 grams, her hatch weight was 26 grams. Maybe he was a very small hatchling and is slowly gaining weight.... I started Enchantress on baby mice everything else was too big for her, she has just now started eating pinky (1-2 day old) rats and they give her a little stretch so I would just check size of mouse/rat before feeding. Good luck and what a handsome boy you're getting!
