Well the idea mainly came about from my viv with the two leo's. Sometimes one decides not to eat crickets, sometimes they both decide not to eat crickets. I can have anywhere between 1-12 crickets. If it's 1 or 2, I usually just leave them in there. But if I have more than that, I like to take them out. They still crap in the cage, die in the water and annoy the leos. I don't like to keep them in there. My beardie generally eats them all, but I won't leave any in there once I turn the lights out.
