The marbled gecko (Christinus marmoratus) is an insect eater. In the wild it hunts moths, spiders, small beetles, and other invertebrates around trees, rocks, and walls at night. If you keep one, mimic that variety with small feeder insects rather than fruit.
About the marbled gecko
This small Australian gecko is nocturnal and climbs well. It is often found under bark, in rock crevices, and around buildings. Adults reach roughly 4 to 5 inches including the tail, so prey must be small.
What marbled geckos eat in the wild
- Moths and other night-flying insects drawn to lights
- Small spiders
- Beetles, ants, and similar small insects
- Insect larvae and other small invertebrates
Offer a rotating mix of pinhead to small crickets, flightless fruit flies for the smallest animals, dubia roach nymphs, and the occasional small mealworm or silkworm. Wild-caught insects are risky because of pesticides and parasites, so buy from a reptile feeder source or breed your own.
Supplements
Dust feeders lightly with calcium powder and use a multivitamin about once a week. Gut-load crickets and roaches with oats, greens, and a commercial gut-load for 24 hours before feeding.
Feeding frequency
Young geckos should eat daily. Adults can be fed two or three times a week. Offer several insects at dusk, watch for 15 minutes, then remove those left over.
Water
Lightly mist the enclosure in the evening so your gecko can lick droplets, and provide a very shallow water dish. Let the enclosure dry between mistings.
Parasites in wild geckos
Wild reptiles can carry parasites. If you bring in a wild-caught marbled gecko, or yours has weight loss despite eating, ask a reptile vet to run a fecal test.

Bottom Line
Marbled geckos are insectivores. Offer small, varied, gut-loaded insects dusted with calcium, keep water available, and see a vet if your gecko loses weight.
