They need no ventral heat or UV light. Temp range 68-77 degrees F. Feed on primarily slugs but earthworms are preferred for availability. They are mostly nocturnal feeders. I would leave mine in a Tupperware container with worm bits and let them feed overnight. Subtrate: Cypress mulch and potting soil mix (50:50) or just cypress mulch with soil on one side. They can get skin lesions if too moist but can also dehydrate on carpet/turf.
