I wouldnt get to many, just incase your leo wont eat them. I would get like a tub of 50 mealies, petco and other pets stores sell them. If your leo likes them then you can get more, wouldnt want to buy 500+ and have your leo not want them.rob.r said:iv been feeding my adult gecko crickets and i want to start on mealworms how much should i get and feed him
