Can African Fat-Tailed Geckos Eat Superworms?

Can a African Fat-Tailed Gecko Eat Superworms?

Yes — a african fat-tailed gecko can eat superworms, dusted with calcium, as part of a varied diet rather than a staple.

Superworms (Zophobas morio) are roughly 20% protein and 18% fat, and they reach about two inches — considerably larger than a mealworm. That size and that fat content are why animals love them.

The number that decides how they should be used is calcium. Superworms carry around 100 mg/kg of calcium. Black soldier fly larvae carry about 9,340 mg/kg — roughly ninety times more. A superworm is a rich, filling feeder that supplies almost no calcium at all, which is why dusting is not a refinement here. It is the whole point.

How Many, and How Often

2–3 dusted superworms twice a week.

The Risk That Matters for a African Fat-Tailed Gecko

This gecko stores fat in its tail and does it efficiently. Superworms accelerate that, so keep them occasional and dust every time.

Why Dusting Matters More Here

Most feeders benefit from a calcium supplement. Superworms depend on it. At around 100 mg/kg they supply almost nothing, and an animal fed heavily on undusted superworms is being fed protein and fat with the calcium left out — which is the direct route to metabolic bone disease in a growing reptile.

What to Feed Instead

The staple should be discoid roaches. Superworms are a supplement to a diet, not the diet.
