I may have to go with the crickets, and split the frogs up for feeding, to ensure the larger frogs don't eat the tiny ones or something. They're currently all in one enclosure, and getting along remarkably well, given their size range - 2 inches for the largest down to about half an inch for the smallest. But separate enclosures for feeding purposes may become necessary, if I do have to switch to crickets. Wish I could find somewhere that sold moths for food! Every single one of the frogs LOVES to eat moths. Everything else seems to be pretty meh to them. =\
