My lizards are about 10 inches long. We are having trouble getting 1 of them to eat enough crickets. I have a delivery of smaller crickets coming tomorrow, to see if that will help, but I want to get some PW too. I've never used them before, though, so don't know what size. Help? And, is Worm Man an ok place to order from? If not, can you rec one that sells smaller quantities?
