Feeding Small Reptiles: An Overview
Small reptiles, such as juvenile geckos, anoles, and small skinks, have unique dietary needs that differ from larger species. Their small size requires appropriately sized prey, often called micro-prey, to ensure they can capture and digest their food safely. This guide covers the types of micro-prey available, nutritional considerations, feeding frequency, and essential supplements.
Recommended Micro-Prey Types
Pinhead Crickets
Pinhead crickets are newly hatched crickets, measuring about 2-3 mm. They are a staple for many small reptiles due to their high protein content and movement, which stimulates hunting instincts. They are widely available and can be gut-loaded before feeding to enhance nutritional value.
Drosophila (Fruit Flies)
Flightless fruit flies (Drosophila hydei or melanogaster) are excellent for tiny reptiles like hatchling geckos and small anoles. They are easy to culture and provide a good source of protein and fat. Ensure the flies are not too large for the reptile's mouth.
Micro Mealworms
Micro mealworms (small mealworms) are suitable for slightly larger small reptiles. They are rich in protein but high in fat, so they should be fed as part of a varied diet. They can be offered in small quantities to avoid overfeeding.
Buffalo Worms
Buffalo worms (lesser mealworms) are tiny beetles in their larval stage. They are smaller than regular mealworms and have a softer exoskeleton, making them easier to digest. They are a good choice for reptiles that need a higher calcium-to-phosphorus ratio.
Black Soldier Fly Larvae
Black soldier fly larvae (BSFL) are nutrient-dense, especially in calcium. They are available in small sizes and do not need dusting with calcium powder. They are an excellent micro-prey for growing reptiles.
Feeding Frequency and Portion Sizes
The amount and frequency depend on the age and species of the reptile. As a general rule, juvenile reptiles should be fed daily or even twice daily, while adults may be fed every other day. Offer as many micro-prey as the reptile can eat in a 10-15 minute session. Remove uneaten prey to prevent stress or injury to the reptile.
| Age | Feeding Frequency | Number of Micro-Prey per Feeding |
|---|---|---|
| Hatchlings/Juveniles (0-6 months) | 1-2 times daily | 5-10 pinhead crickets or equivalent |
| Subadults (6-12 months) | Once daily | 10-15 micro-prey |
| Adults (12+ months) | Every 1-2 days | 15-20 micro-prey |
Nutritional Requirements
Small reptiles require a balanced diet with adequate protein, fat, calcium, and vitamins. Most micro-prey are naturally low in calcium and high in phosphorus, so supplementation is critical. Dust micro-prey with a calcium powder (with and without D3) and a multivitamin powder according to the product instructions. Gut-loading prey with nutritious foods like fruits, vegetables, and commercial gut-load diets improves the prey's nutritional profile.
Harmful Foods and Ingredients
Never feed wild-caught insects, as they may carry parasites or pesticides. Avoid large prey items that can cause impaction or injury. Do not feed fireflies, as they are toxic to reptiles. Also avoid feeding prey that are too large for the reptile to swallow.
Hydration and Water
Provide a shallow water dish with fresh water daily. Small reptiles may also drink from droplets on leaves, so misting the enclosure can help. Ensure the water dish is shallow enough to prevent drowning.
Supplements
In addition to calcium and multivitamins, some reptiles benefit from probiotics or vitamin D3 if not exposed to UVB lighting. Always consult a veterinarian for specific needs.
Feeding Differences by Life Stage
Juveniles need more frequent feedings and higher protein for growth. Adults require less frequent feedings to avoid obesity. Older reptiles may need softer prey or supplements to support joint health.
Signs of a Healthy Diet
A well-fed small reptile will have clear eyes, healthy skin, proper growth, and active behavior. Signs of poor nutrition include lethargy, weight loss, soft bones (metabolic bone disease), and poor appetite. Regular vet check-ups are recommended.
