How To Feed Your Crested Gecko Mango

There are two ways you can feed mangoes to your crested gecko.

Peel and Slice

First, peel and slice the mango into tiny pieces. Make sure to discard the seed. Place the sliced mangoes into your crested gecko’s dish.

Make sure the pieces are not too large or they might cause your pet to choke. The pieces should be smaller than the size of their head as a good measure.


This is the best way to feed mangoes to baby and juvenile crested geckos. It goes down their throat easily and gets digested quickly.

You can blend mango alone or with other fruits such as bananas, blueberries, watermelon, raspberries, strawberries, and blackberries.

You can also blend mangoes with insects (dubia roaches and crickets) and larvae (calci worms, superworms, and hornworms) to further boost the nutritional content.

How Many Times Should Mango Be Fed To It?

Mangoes should be fed 1-3 times a week or two. That’s more than enough for baby, juvenile, and adult crested geckos.

How Many Mangoes Can You Feed It?

You can’t feed a single mango to a crested gecko. It won’t be able to eat everything and will go to waste.

Cutting it into small pieces (5-8 for adults, 3-4 for juveniles, and 1-3 for hatchlings) is the recommended amount.

If you plan on blending the mango, 20-80ml should be the quantity given.

How Calcium To Phosphorous Ratio Affects Your Crestie

Crested geckos should eat a diet that has a Ca:P ratio of 2:1, 1:1, or 1:0.5. The ratio you decide to feed your gecko can affect their growth, metabolism, and health.

If the gecko consumes calcium above what it needs, it is excreted in its urine.

If they consume too much phosphorus, they store it in their bones and teeth, which can lead to problems like kidney stones and metabolic bone disease.

What Is The Ratio Of Calcium To Phosphorus In Mango?

The ratio of calcium to phosphorus in mango is 1:1. Which indicates that there is an equal amount of phosphorus as calcium in the mango.

How To Calculate Ca:P Ratio

You can figure this out by calculating the Ca:P ratio using the formula given below.

According to the nutritional content, the Ca:P ratio is 16.5mg:18.2mg. Dividing through by 16.5 (calcium). The ratio becomes 1:1.

How Does Oxalic Acid Affect Your Pet?

Oxalic acid is not a nutrient or essential dietary component and it is not required for normal growth or health.

When oxalic acid is consumed, it binds to the calcium and magnesium in the body and prevents them from being absorbed.

This can lead to calcium deficiency which can be harmful to your pet. Crested geckos are strict insectivores and may not benefit from the oxalic acid in the food and may not be able to digest it.

Some people recommend soaking and rinsing the fruits to get rid of the oxalic acid. However, this is not proven to be effective.

What are the Oxalic Acid Levels In Mango?

Mangoes are low oxalic fruits that contain 2mg of oxalic acid per serving.

The low amount of oxalic acid won’t cause health problems to your crested gecko.


Mango is a juicy nutritious fruit that’s packed with minerals, and vitamins and keeps your crested gecko healthy.

It doesn’t have high acidic levels that might pose a problem to your pet. In short, yes, your crested gecko can eat mangoes and it’s perfectly safe to add to its diet.
