My dragons eat 40-60 a day. I can't imagine one of my leo's eating 20 in a day, but you're talking about small mealworms so there is a big difference. My full grown leo's eat just a few large meal worms every night. I also give them crickets.

I leave mealworms in usually all the time. I have a large abundance of them, I would LOVE if they would eat 20 a day. Hell, I'd love if they'd eat 100 a day!
