Do Crested Geckos Eat Other Geckos?

While it’s not their primary food source, crested geckos sometimes show cannibalistic behavior.

So, yes, they can, but it is rare and usually occurs when food is scarce or when there is competition for territory.

Here’s why:

  • Opportunistic feeders: Crested geckos are generally not aggressive hunters, but they will take advantage of easy prey items. If a smaller gecko, especially a hatchling, enters their territory, they may see it as a meal.
  • Survival mode: When food is particularly scarce, a crested gecko might be more inclined to cannibalize another gecko.
  • Territorial conflicts: In overcrowded enclosures, a dominant gecko might injure and potentially eat a weaker one to keep control over space and resources.

However, this does not happen very often.

As I mentioned above, they only do this when they are very hungry or when they want to protect their home from other lizards.

That’s why: never house adult crested geckos with juveniles or geckos significantly smaller than themselves. The risk of one eating the other is too high.

Hope this makes sense!
