Yeah. They get quite the appetite when they reach adult size. My guys, who are adult size, eat 6-10 crickets a day. Lol.
Good luck.
My 2 young ones are worse then my adult. I feed him as much as he'll eat in an hour once a week but the 2 young ones never seem to be full and I don't want to be as strict on their feeding schedule if they are still growing.
