Gargoyle geckos are omnivorous frugivores, which sets their nutritional profile apart from the insect-only diets many keepers associate with lizards. In the wild they consume a mix of nectar, soft ripe fruit, tree sap, and small invertebrates, and the best feeding programs in captivity mirror that balance rather than leaning entirely on live prey. The cornerstone of a healthy gargoyle gecko diet is a complete meal-replacement powder formulated specifically for fruit-eating geckos, which supplies protein, fat, vitamins, and minerals in the correct ratios.
Protein and fat needs are moderate rather than high. Growing juveniles and gravid females require more frequent feeding and slightly richer formulas, while mature adults do well on a steady maintenance diet that prevents the obesity that sedentary captive geckos are prone to. Calcium and vitamin D3 are the two most important micronutrients to track, because chronic shortfalls lead to metabolic bone disease, one of the most common and most preventable health problems in captive geckos.
Hydration is also a nutritional consideration. Gargoyle geckos take much of their water from droplets on enclosure surfaces and from the moisture in their food, so a diet built around hydrated powder mixes and the occasional juicy insect supports both nutrition and fluid intake at the same time.
