There main staple is Canadian nightcrawlers, my cranwellis wont eat crickets anymore but my ornate will so I give crickets every once in awhile to change it up. And then every couple weeks i will treat them hornworms, silk worms, waxworms or butter worms, what ever is available at the store at the time. And no I don't give them all those at once, they get one or other. And 2 are adult and 1 sub adult so every few months I will give them a pre killed fuzzy and when they were small I would give pinkies every once awhile.
