If I don't get mealworms I get the super worms and I feed it to my gecko as well. Two super worms fill her up, but I have to feed her close to 10 mealworms for that to fill her up. And the super worms really filled my Beardie up, and she just loooovveeddd them LOL. I'm thinking about buying the supers in bulk. I used to keep mealworms in bulk, and raise them to make beetles then produce more mealworms (which never happened, the beetles bred but I didn't get any eggs or baby mealworms). I'm assuming the supers are very similar to care for like the mealworms. Right now I have the supers in oatmeal and crushed bran. That's what I kept my beetles and my mealworms in last time I kept them and they did just fine.
