I ordered small BSFL and I probably should have gotten medium. They don’t attract my dragons attention. I have had them for about a week now and he just walks by them. I feel like if they were bigger it would interest him more. How can I get these things to grow quickly? I threw some veggies and bread crumbs in there, but the are all around the same size. I hate to waste all these bugs! Let me know if there is something that I can do...thanks!
