Crested Gecko Diet – In The Wild vs In Captivity

Can Crested Geckos Eat Apples

Before exploring can Crested geckos eat apples and what are the benefits and negatives, you need to be familiar with their diet in the wild and in captivity.

In their natural habitat, on the island of New Caledonia, the Crested gecko’s diet consist of the following components:

  • Insects 49.6%
  • Fruits 11.7%
  • Fruit nectars 7.52%
  • Seeds 1.8%
  • Pollen 10.3%

In the wild, fruits and fruit nectar is part of the Crested gecko’s diet. However, when kept as pets, fruit should only be fed in moderation.

One of the reasons for that is – if your Crested gecko is on a commercial diet, they will be getting all the nutrient they need from their main food source and won’t need any fruits added to their nutrition.

Although, fruits are part of the Crested gecko’s diet in the wild, when kept as pets fruits shouldn’t be fed too often.

Essential knowledge for any Crested gecko owner is understanding the factors that make a fruit safe to feed to your gecko. This information is especially important to know as some fruits are even dangerous and should be avoided all together.

The following are factors that affect how healthy a fruit is for your Crested gecko’s diet:

  • Calcium to phosphorus ratio (Ca:P). Foods that have a 2:1 (or better) calcium to phosphorus ratio are considered good
  • Oxalic acid. In people, the consumption of additional oxalic acid may result in stone formation in the urinary tract. Similarly, Crested geckos should avoid eating foods with a medium to high levels of oxalic acid

As most fruits don’t have a desirable Ca:P ratio, they can’t be included as a staple diet.

However, that doesn’t mean you can’t feed your Crested gecko any fruits. Depending on the fruit’s nutrition and type, it can be either:

  • Fed to your gecko more often
  • Served only as an occasional treat
  • Never fed to your gecko as it can be dangerous to their health

  • Mashed. After the apples have been cooked and have softened, you can mash/blend them and serve in a puree form
  • Rotten. By allowing the apple to rot and become overripe, the fruit will naturally soften and will be easy for your gecko to bite on. In the wild, this is how Crested geckos will eat the fruit they find on the ground and they love it!

  • High to moderate Ca:P
  • Low levels of oxalic acid
