Crested Gecko Diet – In The Wild vs In Captivity

Can Crested Geckos Eat Vegetables

Before looking at what are safe vegetables to feed your Crested geckos, it’s important to know what they eat in their natural habitat.

Not all geckos can eat vegetables as some are strictly insectivores. But what about the Crested gecko?

Native to the island of New Caledonia, the Crested geckos are known for eating the following diet:

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

As Crested geckos are omnivorous, there are two diet options when kept as pets:

  • Commercial diet. A commercial diet is the easiest option. The formula is designed to provide your Crested gecko with all the nutrients they need to be healthy and thrive. Therefore, they won’t need any vegetables added from a nutritional point of view
  • Homemade diet. If you have decided to go down the route of homemade diet, you must do enough research into how much and how often you should feed them a variety of insects, fruits and vegetables. Providing your Crested gecko with a well-balanced homemade diet is not an easy job and it’s not recommended for beginners unless you have done extensive research beforehand

Many types of vegetables can still be part of the Crested gecko’s diet either as:

  • An occasional treat. Even if your Crested gecko is on a commercial diet, you can still give your Crested geckos vegetables as an occasional treat
  • Homemade diet. If you are experienced enough and have decided to go down the route of a homemade diet, then vegetables will need to be included in your Crested gecko’s regular feedings. However, only certain vegetables can be used in a daily diet as some are considered unsafe for frequent consumption due to their poor nutritional value

What Makes A Vegetable Safe For Crested Gecko

The factors to look at when deciding if a vegetable is safe are:

  • Ca:P ratio
  • Oxalic acid levels
  • Vitamin A content
  • Goitrogens content

With that said, safe and healthy vegetables that you can include in your Crested gecko’s staple diet and feed more often than an occasion treat will be:

  • High in calcium
  • Have a good Ca:P ratio of 2:1 or better

On the other hand, vegetables that have a bad Ca:P ratio can only be fed as an occasional treat. If you feed your gecko vegetables with bad Ca:P ratio too often, it can lead to the development of a well-known illness – Metabolic Bone Disease.

Can Crested Geckos Eat Vegetables

As mentioned earlier, in the wild Crested geckos eat a varied diet that includes vegetables and plants.

However, when kept as pets, you can either feed your Crested gecko a commercial diet and give them vegetables only as an occasional treat or have them on a homemade diet which includes vegetables amongst other foods.

Before including vegetables in your Crested gecko’s diet, let’s look at the benefits and negatives of feeding your Crested gecko vegetables.

Positives

  • Vitamin A – This is a key vitamin that helps maintain a healthy reptile diet. Vitamin A is essential for the functions of the skin, mucous membranes, retina (part of the eye), muscles, immune system, reproductive system and more
  • Source of fibre – Helps maintain bowel health
  • Calcium – calcium helps maintain and develop strong bones. In addition, the heart, muscles and nerves also need calcium to function properly. Calcium is especially important for juveniles and gravid (pregnant) female geckos
  • Source of iron – Iron helps to preserve many vital functions in the body, including energy, gastrointestinal processes, the immune system, and help with the regulation of body temperature

Negatives

  • Insecticide or pesticide  can residue on the vegetables which is toxic to your Crested gecko
  • As you’ll be buying the vegetables from your local store, domesticated vegetables will have less vitamins and minerals
  • Goitrogens – Goitrogens inhibit the absorption of iodine. The consumption of Goitrogens over a long period of time can result in the development of hypothyroidism. Symptoms of hypothyroidism include lethargy, slow growth, and can even be fatal. The goitrogens affect the thyroid and can make it difficult for the thyroid to produce the hormones that your Crested gecko needs to be healthy
  • Oxalic acid – foods with high levels of Oxalic acid shouldn’t be fed to your Crested gecko

Can Crested Geckos Eat Vegetables – Conclusion

After looking at positives and negatives of can Crested geckos eat vegetables, let’s take a look at:

  • Vegetables with good Ca:P ratio
  • Vegetables with bad Ca:P ratio
  • What vegetables to avoid feeding your Crested gecko

Vegetables With Good Ca:P ratio

Vegetables that have good Ca:P ratio can be:

  • Included in a staple homemade diet
  • Fed to your Crested more often than just an occasional treat

The following is a list of vegetables with good Ca:P ratio:

  • Dandelion Greens – Ca:P is 2.8:1 Dandelion leaves provide a good source of Calcium, Vitamin A and K. If taken from the garden, you should avoid picking any that may have been in contact with pesticides or other chemicals. Also, you should not pick dandelion leaves that are near the roadside
  • Rocket Ca:P is 3.1 : 1. A good source of vitamin A and Calcium
  • Mustard Greens – Ca:P is 2.4 : 1. Very high vitamin A, vitamin C, high Calcium and Potassium
  • Watercress – Ca:P is 2.0: 1. It contains good levels of Iron, Calcium, Iodine, Folic acid, Vitamins A and C
  • Endive – Ca:P is 1.9 : 1. High in Calcium and Vitamin A
  • Celery – Ca:P is 1.7:1. High in calcium and low in goitrogenic compounds, celery can be a vegetable in your Crested gecko’s staple diet within your crested geckos diet
  • Butternut squash – Ca:P is 1.5:1. It’s high in Vitamin A and Calcium

It’s important to note that even the most nutritious vegetables shouldn’t be given as the main source of food. The Crested geckos need additional vitamins and minerals in their diet that can’t be provided by vegetables only.

Vegetables With Bad Ca:P ratio

Vegetables with bad Ca:P ratio can’t be included in a homemade staple diet for your Crested gecko and should only be fed as an occasional treat once a month.

  • Carrots – Ca:P is 0.6:1. Carrots have little calcium but have high levels of carotenes
  • Chard –  Ca:P is 1.1:1. This is a good source of fibre, Vitamin A, C, E, K, Calcium and Iron
  • Cos/Romaine Lettuce – Ca:P is 0.8:1 good source of Vitamin A and fibre. Aside from Iceberg lettuce, most green leaf and romaine lettuces contain good amounts of  vitamins & minerals. In addition, lettuces aren’t high in goitrogens or oxalates which makes them good to feed to your Crested gecko
How To Make Foods With Bad Ca:P ratio Into A Good Meal

Although, there are many vegetables that have a bad Ca:P ratio, there is a way to still make the serving of those vegetables nutritional.

The way to do that is by:

  • Adding other vegetables that will provide nutritional value to the meal such as rocket or watercress
  • Sprinkle some CGD powder which will add calcium and vitamins to the meal

Vegetables To Avoid Feeding To Your Crested Gecko

  • Broccoli – Broccoli is best avoided as it is high in oxalates and goitrogens
  • Spinach – High in oxalates and goitrogens so should be used occasionally
  • Cabbage – High in goitrogens and oxalates
  • Cauliflower – Too high levels of goitrogens and oxalates
  • Kale – High in goitrogens and oxalates
  • Avocado – Avocados are toxic to Crested geckos and should never be fed

  • Good Ca:P ratio vegetables can be given to your gecko as a part of their staple diet and more often than an occasional treat once a month
