Crested geckos (Correlophus ciliatus) are the “teddy bears” of the gecko world—with their soft, velvety skin, expressive crest-like eyelashes, and charmingly clumsy jumps. Once thought extinct until their rediscovery in New Caledonia in 1994, they’ve since become one of the most popular pet reptiles on the planet. But their diet can confuse even experienced keepers. “How often should I offer fruit puree versus commercial crested gecko diet? Can my gecko survive on fruit alone?” Let’s uncover the precise nutritional balance these nocturnal charmers need to thrive.

The Crested Gecko Diet Revolution: CGD vs. Homemade Purees

In the wild, crested geckos are frugivorous omnivores, meaning they eat primarily soft, overripe fruits and the occasional insect. They lick nectar, fruit pulp, and pollen from rainforest plants. In captivity, the game changed with the invention of Crested Gecko Diet (CGD)—a complete powdered meal replacement that, when mixed with water, provides everything a gecko needs: protein, vitamins, minerals, and carbohydrates in one balanced formula. Think of CGD as a nutritionally complete smoothie and homemade fruit puree as a delicious but incomplete dessert.

The Core Rule: CGD Is the Staple, Fruit Is the Treat

Key Points:

• CGD feeding frequency: Offer fresh CGD every 2–3 days for adults, and every 1–2 days for growing juveniles and breeding females. Replace uneaten CGD within 24–36 hours to prevent spoilage.
• Fruit puree frequency: Offer fruit puree once per week as a treat, replacing one CGD feeding that day. This is the maximum safe frequency—any more and you risk nutritional imbalances.
• Portion size: For an adult gecko, offer about 1/4 to 1/2 teaspoon of fruit puree in a shallow feeding dish. Crested geckos have tiny stomachs and will self-regulate intake.
• Rotation matters: Rotate between mango, papaya, fig, apricot, banana, and pear puree from week to week. Each fruit brings a different vitamin and antioxidant profile to the table.

“My crested gecko, Nori, goes absolutely bonkers for mango puree—he’ll launch himself from his cork bark the moment he smells it. But I learned the hard way that feeding fruit more than once a week made him refuse his CGD entirely. He became a picky eater and started losing weight. Now fruit night is a special Friday ritual, and he eats his CGD normally the rest of the week.” — Sarah M., crested gecko keeper.

Safe Fruits for Crested Gecko Purees

Not all fruits are created equal for crested geckos. In the wild, they encounter soft, tropical fruits that are high in natural sugars and low in acid. Your fruit choices should mirror this.

Best fruits (safe and nutritious):

• Mango (high in vitamin A, naturally sweet)
• Papaya (excellent calcium-to-phosphorus ratio)
• Fig (rich in calcium and fiber, a wild diet staple)
• Apricot (high beta-carotene for vivid coloration)
• Banana (use sparingly—high in phosphorus, may bind calcium)
• Pear (gentle on digestion, hydrating)
• Peach (nectar removed, rich in vitamin C)
• Melon (cantaloupe and honeydew—high water content, good for hydration)
• Blueberries (antioxidant-rich, mash thoroughly—whole berries are a choking hazard)

Fruits to avoid or limit strictly:

• Citrus fruits (orange, lemon, lime, grapefruit): Too acidic—can cause mouth irritation and digestive upset. A tiny drop of orange juice mixed into CGD is occasionally used to entice picky eaters, but never offer citrus fruit chunks or puree.
• Avocado: Contains persin, which is toxic to many animals including birds and potentially reptiles. Although the risk to geckos is not fully studied, it’s best avoided entirely.
• Rhubarb: High in oxalic acid, which binds calcium. Toxic in large amounts.
• Grapes: Controversial—high oxalate content and a choking hazard. If you offer them, peel completely and mash to a smooth consistency.

How to Prepare the Perfect CGD/Gecko Puree

• Use a high-quality CGD brand: Pangea and Repashy are the gold standards. Their “with insects” formulas (like Pangea Growth & Breeding or Repashy Grubs ‘N’ Fruit) provide additional protein for growing geckos.
• Mix CGD with water to a ketchup-like consistency—smooth, thick enough to hold its shape in a dish, but not so thick it dries out within hours.
• For homemade fruit puree: Blend fresh, ripe fruit with a tiny splash of water until completely smooth. Strain through a fine-mesh sieve to remove any fibrous bits or seeds that could cause impaction.
• Never add sugar, honey, yogurt, or baby food to gecko purees. These are loaded with preservatives and incorrect nutrient ratios. Baby food in particular has caused severe metabolic bone disease in geckos when used as a diet staple.
• Serve at room temperature. Cold puree straight from the fridge can shock your gecko’s system and may be refused.

The Insects Question: Should Crested Geckos Eat Bugs?

Crested geckos don’t strictly need live insects if they’re on a high-quality CGD with insect protein, but offering gut-loaded, dusted crickets or dubia roaches 1–2 times per week provides enrichment, exercise through hunting, and a natural protein boost. For growing juveniles and breeding females, live insect feedings are highly recommended.

Key Points for Insect Feedings:

• Feed appropriately sized insects (no larger than the space between the gecko’s eyes)
• Gut-load insects for 24 hours before feeding
• Dust with calcium powder (without D3) once per week for geckos already on CGD
• Never leave uneaten crickets in the enclosure overnight—they can bite your gecko

Seasonal Adjustments: Breeding Season and Winter

• Breeding females: Increase CGD feeding to every 1–2 days. Add an extra insect feeding per week. Egg production demands significantly more calcium and protein. Consider switching to a “Growth & Breeding” formula during this time.
• Winter cooling period: Many keepers provide a slight nighttime temperature drop to 65–68°F (18–20°C). During cooler months, geckos naturally eat less. Offer fresh CGD every 3–4 days and skip the fruit puree—there’s no need to tempt an appetite that’s naturally suppressed.
• Summer activity peak: During warmer months when geckos are most active, you can increase fruit puree to twice per week if your gecko maintains a healthy weight. Watch body condition closely.

Signs of Nutritional Imbalance

• Overweight/flabby: The belly appears disproportionately wide compared to the head and limbs. Reduce fruit to once every 2 weeks and feed smaller CGD portions.
• Underweight/thin: The hip bones and spine are visible. Increase CGD frequency and add insect feedings. Consult a reptile vet if weight loss persists.
• Floppy tail syndrome (FTS): The tail flops to one side when the gecko hangs upside down—a skeletal deformity linked to calcium imbalance and genetics. Ensure proper CGD formula (not fruit-heavy) and adequate calcium supplementation.
• Dull coloration and poor shedding: Often a sign of vitamin A deficiency. Rotate fruits like mango and apricot, which are high in beta-carotene, and ensure your CGD is fresh (not expired).

Fun Fact: The “Eyelash” Gecko That Laps Its Own Eyeballs

Crested geckos lack eyelids—they can’t blink! Instead, they use their long, flexible tongue to lick and clean their eyes, keeping them moist and debris-free. It’s one of the most endearing (and slightly alien) behaviors in the reptile world. This is also why humidity is so critical—without it, their exposed eyes can dry out. When you see your gecko doing the “eye lick,” you’re watching a behavior that’s been perfected over millions of years in the humid rainforests of New Caledonia.

Conclusion

Crested geckos are wonderfully low-maintenance eaters compared to many reptiles, but the key to their health is balance, not variety for variety’s sake. CGD should make up 80–90% of their diet, with fruit puree as a once-weekly treat and live insects as an optional protein supplement. The danger comes not from feeding fruit, but from letting fruit displace the complete nutrition in CGD. Stick to the formula, rotate your fruit choices, watch your gecko’s body condition, and you’ll have a happy, healthy, long-lived companion whose only complaint will be that mango night doesn’t come often enough!
