Best African Fat-Tailed Gecko Food: Complete Guide

African fat-tailed geckos are one of the most rewarding reptiles you can keep. They're calm, hardy, and absolutely gorgeous. But getting their diet right is essential — these geckos can be surprisingly picky, and feeding mistakes are one of the top reasons owners run into health problems.

This guide covers everything you need to know about the best African fat-tailed gecko food. From staple feeders to supplements, feeding schedules to what to avoid — you'll have everything you need to keep your gecko healthy for years.

What Do African Fat-Tailed Geckos Eat?

In the wild, African fat-tailed geckos (Hemitheconyx caudicinctus) live in the savanna grasslands of West Africa. They're insectivores — meaning they eat only insects and other invertebrates.

You won't see them eating fruit or vegetables. Their digestive systems simply aren't built for it. If you own a leopard gecko, the feeding approach is very similar — both species come from dry, semi-arid environments and hunt similar prey.

In captivity, their diet should mirror what they'd find in the wild: live insects, gut-loaded and dusted with supplements. That's really the whole formula.

The Best Feeder Insects for African Fat-Tailed Geckos

Not all insects are equal. Some are nutritional powerhouses. Others are fine as occasional treats. Here's what you need to know about each option.

Crickets — Best Everyday Staple

Crickets are the classic choice for good reason. They're widely available, affordable, and your gecko will chase them with enthusiasm. That hunting behavior is actually great mental stimulation — it keeps your gecko active and engaged.

A healthy adult AFT gecko should eat 6–10 appropriately sized crickets per feeding. The cricket should be no wider than the space between your gecko's eyes. Any bigger risks choking or gut impaction.

Always gut-load your crickets for 24–48 hours before feeding. More on that in a moment.

Dubia Roaches — Top Recommendation

Honestly, dubia roaches might be an even better staple than crickets. Here's why so many experienced keepers have switched:

• Higher protein content than crickets
• Better calcium-to-phosphorus ratio
• They don't jump out of the enclosure
• They don't chirp at night
• They live longer, so you waste fewer insects

If crickets are driving you crazy, switch to dubias. Your gecko won't complain. Feed the same amount — 6–10 per session for adults.

Mealworms — Occasional Treat Only

Mealworms are fine as an occasional treat, but don't make them a staple. They're high in fat and low in protein compared to crickets or dubias. Too many mealworms leads to obesity, which is a real and common problem in captive AFT geckos.

Limit mealworms to once a week at most. They work well as a high-value reward when you're working on taming a new gecko.

Superworms — Treat, Adults Only

Superworms are bigger and fattier than mealworms. They're fine for adult geckos as a rare treat — maybe once every two weeks. Don't feed them to juveniles or underweight geckos. One more thing: a superworm's jaws can bite back, so watch closely when feeding these.

Black Soldier Fly Larvae — Hidden Gem

Black soldier fly larvae (sold as Phoenix Worms or Calci-Worms) are a fantastic occasional feeder. They're naturally so high in calcium that some keepers don't even dust them. They're also soft, easy to digest, and great for geckos recovering from illness or females in egg-laying season.

Hornworms — Hydration Boost

Hornworms are mostly water, making them a great tool when your gecko seems dehydrated or is reluctant to drink. They're low in fat and easy to digest. Feed them as an occasional treat — roughly every two weeks.

Waxworms — Rare Treat Only

Waxworms are basically candy for geckos. They're extremely high in fat and can become addictive. Once a gecko gets a taste for waxworms, they sometimes refuse other feeders entirely.

Save waxworms for:

• Breeding females that need extra calories
• Underweight geckos rebuilding fat reserves
• Geckos recovering from illness

For healthy geckos, limit to 2–3 waxworms no more than once a month.

How to Gut-Load Your Feeders

Gut-loading means feeding your feeder insects nutritious food before offering them to your gecko. The insects pass those nutrients along when your gecko eats them. It's one of the most important — and most overlooked — parts of reptile nutrition.

Feed your crickets and dubia roaches a mix of:

• Fresh vegetables: collard greens, kale, sweet potato, carrots, squash
• Commercial gut-load: products like Repashy Bug Burger make this easy
• Grains: oats or wheat bran

Gut-load for at least 24 hours before feeding. 48 hours is even better. Avoid citrus, iceberg lettuce, and spinach — these have poor nutritional value or can block calcium absorption.

A well-fed cricket is a far more nutritious meal than a cricket that's been sitting in an empty cup for a week.

Calcium and Vitamin Supplements

This is where many new keepers cut corners — and it always catches up with them. AFT geckos need supplements at every single feeding.

Calcium Without D3 (Every Feeding)

Dust feeder insects with calcium powder without D3 at every single feeding. Without enough calcium, AFT geckos develop metabolic bone disease (MBD) — a painful, progressive condition that's entirely preventable.

If your gecko has access to UVB lighting, calcium without D3 is the right daily choice. D3 can accumulate to toxic levels if overdosed.

Calcium With D3 (Twice Monthly)

Use calcium with D3 twice a month if your gecko doesn't have UVB lighting. D3 helps the body absorb calcium properly. Without UVB or D3, calcium supplementation alone won't stop MBD from developing.

Reptile Multivitamin (Twice Monthly)

Add a reptile multivitamin twice a month. This covers vitamin A, B vitamins, and trace nutrients that gut-loaded insects may not fully supply on their own.

How to Dust Feeders

Place insects in a small bag or cup with a pinch of supplement powder. Give it a gentle shake until they're lightly coated. Then offer them to your gecko immediately — supplements fall off within minutes, so don't let coated insects sit around.

African Fat-Tailed Gecko Feeding Schedule

How often you feed depends on your gecko's age and life stage:

Always feed your gecko in the evening. AFT geckos are crepuscular — most active at dusk and dawn. Evening feeding mimics their natural hunting window and gets you the best feeding response.

Watch your gecko's tail to gauge body condition. A healthy tail is plump but not swollen. The tail stores fat reserves — like a camel's hump. A thin, deflated tail signals underfeeding or illness. A very thick, lumpy tail means too many fatty feeders.

Hydration: Don't Overlook It

Fresh water must be available at all times. Use a shallow reptile water dish — small enough that your gecko can't fall in and get stuck.

Change the water daily. Bacteria builds up fast in a warm enclosure.

You can also lightly mist one side of the enclosure a few times per week. AFT geckos come from higher-humidity environments than leopard geckos. They'll appreciate it. If you see your gecko licking droplets off the glass walls, that's a clear sign it wants more humidity or water.

Hornworms are also an excellent hydration booster for geckos that seem reluctant to drink from a dish.

Foods to Never Feed Your AFT Gecko

Some things look harmless but aren't. Avoid these completely:

• Wild-caught insects — they carry parasites, pesticides, and pathogens
• Fireflies (lightning bugs) — toxic to reptiles, can be fatal even in small amounts
• Fruit and vegetables — AFT geckos are strict insectivores; plant matter won't digest properly
• Avocado — toxic to most reptiles
• Oversized insects — anything wider than the space between their eyes is a choking and impaction risk
• Insects left in the enclosure overnight — live crickets can stress or even injure a sleeping gecko; always remove uneaten feeders after 15–20 minutes

How Many Crickets Should I Feed My African Fat-Tailed Gecko?

This is the question new AFT owners ask most. Here's the simple answer:

Feed as many appropriately sized insects as your gecko will eat in 10–15 minutes. For most adults, that's 6–10 insects per session.

Juveniles eat more frequently but smaller amounts. Hatchlings should be offered food daily. Adults every 2–3 days is plenty.

The tail doesn't lie. Check it regularly and adjust your feeding frequency up or down based on what you see. This is more reliable than sticking rigidly to a number.

Feeding Tips for Picky Geckos

Some AFT geckos are stubborn eaters, especially right after coming home. Here's what actually works:

Give them time. New geckos often don't eat for 1–2 weeks as they settle in. This is completely normal. Keep offering food every 2–3 days and don't panic.

Try different feeders. If your gecko ignores crickets, try dubia roaches. Preferences vary from gecko to gecko.

Check your temperatures. AFT geckos won't eat if the warm side of their enclosure isn't warm enough (85–90°F). Cold geckos don't digest properly and lose their appetite fast.

Feed at night. If you're offering food during the day, your gecko may simply not be in hunting mode yet.

Don't handle before feeding. Stress kills appetite. Give your gecko at least an hour of quiet before offering food.

Quick Reference: Best AFT Gecko Food at a Glance

Getting your AFT gecko's diet right isn't complicated once you know the basics. Stick with dubia roaches or crickets as your staple, gut-load everything, dust with calcium at every single feeding, and rotate in variety with occasional treats. Your gecko's tail will tell you if you're on the right track — keep it plump, and you're doing great.
