Red eyed crocodile skink diet is one of the most important parts of keeping this reptile healthy. Many new owners ask what do red eyed crocodile skinks eat and how often should they be fed. These small reptiles may look like tiny dragons, but their feeding needs are very specific. A wrong diet can quickly lead to weakness, stress, and bone problems.
The red eyed crocodile skink, scientifically known as Tribolonotus gracilis, is a small ground-dwelling lizard from the rainforests of Papua New Guinea. In the wild, it eats insects found in leaf litter and moist soil. In captivity, we must copy this natural diet as closely as possible.
They are strict insectivores. This means they eat insects only. They do not eat fruits, vegetables, or plant matter. Understanding this simple rule is the first step to proper feeding.
What Do Red Eyed Crocodile Skinks Eat in the Wild?
In their natural habitat, these skinks hunt small moving prey. They eat insects, larvae, small worms, and other tiny invertebrates. They use their strong sense of movement to find food on the forest floor.
Wild prey includes beetles, crickets, roaches, larvae, and other soft-bodied insects. These insects provide protein, fat, calcium, and moisture. Because the rainforest is humid, wild insects are naturally hydrated and nutrient-rich.
This natural pattern teaches us something important. A varied insect diet is necessary for good health. Feeding only one type of insect can lead to nutritional imbalance.

Red Eyed Crocodile Skink Diet in Captivity
In captivity, the diet must be simple but balanced. The main rule is live insects only. They respond to movement, so dead insects are often ignored.
The best captive insects must be:
Fresh
Gut-loaded
Appropriate in size
Dust-coated with supplements.
The size of the insect should never be bigger than the space between the skink’s eyes. This prevents choking and digestive stress.
Adult red eyed crocodile skinks usually measure 7 to 9 inches in total length. Hatchlings are around 2 to 3 inches long. Because of this size difference, feeding amounts must change with age.
Best Insects for Red Eyed Crocodile Skink Diet
A healthy feeding plan includes different feeder insects.
Crickets are one of the most common feeders. They are active, which triggers hunting behaviour. They are high in protein but must be gut-loaded before feeding.
Dubia roaches are another excellent option. They are soft-bodied and easy to digest. They contain good protein levels and moderate fat. Many keepers prefer them because they do not jump like crickets.
Black soldier fly larvae are rich in calcium naturally. They are soft and easy to eat. They are especially good for young skinks that need strong bone growth.
Mealworms can be used, but only in small amounts. They have harder shells and more fat. Too many mealworms can cause digestive issues.
Variety is the key to proper nutrition. Rotating between crickets, roaches, and larvae gives better results than feeding only one insect type.
Foods to Avoid Completely

Some new owners try to offer fruits or vegetables. This is not correct.
Red eyed crocodile skinks do not eat fruits or vegetables. Their digestive system is not built for plant matter.
Do not feed:
Fruits.
Leafy greens.
Processed pet food.
Wild-caught insects from pesticide areas.
Wild insects may carry parasites or chemicals. Always use captive-bred feeder insects.
Feeding Schedule by Age
Feeding frequency changes as the skink grows.
Hatchlings from 0 to 3 months old should be fed every day. Their bodies are growing fast. Offer 3 to 5 small insects per feeding session.
Juveniles from 4 to 12 months old can be fed every other day. Offer 4 to 6 small to medium insects each time.
Adults older than 12 months can be fed 3 times per week. Offer 5 to 8 properly sized insects per session.
Overfeeding can cause obesity. A healthy adult should look slightly rounded but not swollen.
If the skink refuses food for 1 or 2 days, do not panic. Stress, shedding, or temperature changes can reduce appetite temporarily.
Calcium and Supplement Guide

In the wild, insects contain natural minerals from soil and plants. In captivity, feeder insects may lack enough calcium. This is why supplements are necessary.
Calcium powder without D3 should be used at most feedings. Lightly dust the insects before offering them.
Calcium with Vitamin D3 should be used 1 to 2 times per week if UVB lighting is weak or absent.
A reptile multivitamin should be used once every 1 to 2 weeks.
Lack of calcium can cause metabolic bone disease. This condition leads to weak bones, shaking limbs, and jaw softness.
Good supplementation supports bone strength, muscle function, and long lifespan of 8 to 12 years.
Importance of UVB and Diet Connection
Even though red eyed crocodile skinks live in shaded forests, low-level UVB lighting is still helpful in captivity.
UVB helps the body produce Vitamin D3. Vitamin D3 allows calcium absorption. Without proper UVB or D3 supplementation, calcium cannot work effectively.
This shows how diet and lighting work together. Food alone is not enough. Proper lighting supports nutrition.
Gut Loading Insects for Better Nutrition
Gut loading means feeding the insects healthy food 24 to 48 hours before giving them to your skink.
Feed insects leafy greens, carrots, squash, and commercial gut-load diets. This improves the nutritional value of the insects.
A well gut-loaded cricket is far more nutritious than a starved one.
Gut loading is one of the most powerful tools for long-term health.

Water and Hydration Needs
Red eyed crocodile skinks live in humidity levels of 70 to 90 percent. They drink small water droplets from leaves and enclosure surfaces.
Light misting once or twice daily helps maintain hydration. A shallow water dish can be provided, but many prefer licking droplets.
Dehydration signs include:
Sunken eyes
Wrinkled skin
Low activity
Hydration is as important as feeding. Insects also provide moisture, especially soft-bodied larvae.
Common Feeding Mistakes
One common mistake is feeding insects that are too large. Large prey can cause choking or internal injury.
Another mistake is skipping supplements. Over time, this leads to bone problems.
Feeding only mealworms is another error. They are fatty and not balanced alone.
Overfeeding adults can cause fat buildup. A healthy adult weighs around 40 to 60 grams depending on size and gender.
Some owners handle the skink during feeding. These reptiles are shy and stress easily. Stress reduces appetite.
Calm, quiet feeding time improves success.
Signs of a Healthy Feeding Routine

A well-fed red eyed crocodile skink shows:
Clear eyes.
Smooth skin.
Strong grip.
Steady movement.
Regular shedding.
Shedding usually happens every few weeks in growing juveniles and less often in adults.
Healthy stool should be firm with a white urate portion. Loose stool may indicate stress or poor diet.
Seasonal Appetite Changes
Sometimes appetite changes during cooler months. If enclosure temperature drops below 72°F at night or below 75°F during the day, digestion slows.
Ideal daytime temperature is 75 to 82°F. Night temperature can drop to 70 to 72°F.
Stable temperature supports stable digestion.
How Does Diet Affect Lifespan?
With correct feeding, supplementation, and humidity control, red eyed crocodile skinks live 8 to 12 years in captivity.
Poor diet shortens lifespan. Nutrient imbalance weakens the immune system. Weak immunity leads to infections and slow recovery.
Balanced insect variety, proper calcium, and hydration directly affect longevity.
Red eyed crocodile skinks are unique reptiles with very specific feeding needs. Their diet must stay simple and natural. They eat live insects only. They need calcium, occasional Vitamin D3, and proper gut loading.
Feeding schedule changes from daily for hatchlings to 3 times weekly for adults. Insect size must always match body size. Clean water and high humidity support digestion and health.
A varied insect diet with proper supplements keeps them strong for 8 to 12 years.
If you want your red eyed crocodile skink to stay active, strong, and healthy, focus on correct feeding from day one. Follow this guide carefully and create a stable routine that supports long-term growth and wellbeing.
