Factors to Consider Before Feeding Fruits to Your Crested Geckos

Calcium-phosphorus ratio

The ratio of calcium-phosphorus is a major factor that determines what your gecko gains from fruits. Calcium helps strengthens the bones and helps prevent bone-related deficiencies. Foods that have a higher amount of calcium than phosphorus will benefit your crested gecko.

However, foods with a low-high calcium-phosphorus ratio could cause Metabolic Bone Disease (MBD) in crested geckos.

Oxalic acid content

Fruits with high oxalic acid content shouldn’t be a regular in your crested gecko’s diet. Include fruits that are low in oxalic acid to ensure your reptiles don’t come down hard with nasty illnesses. Citrus fruits like tangerines and oranges should not be regulars for your crested gecko. Most, if not all, citrus fruits are high in oxalic acid.

Sugar content

Fruits high in natural sugars could become an addiction for crested geckos. Refrain from feeding your crested geckos fruits they may become addicts to. Some fruits and berries could make your crested gecko avoid eating food, which may affect its overall health.

Nutritional benefits

As expected, the nutritional compositions of fruits have several differences. You have to check out the nutritional benefits of each fruit in your gecko’s diet. If there is no real benefit for your crested gecko, it’s better to stop feeding such fruits to your reptile.

Vitamin C content

Foods with high vitamin C content should not be a regular part of your gecko’s meals. Excess vitamin C in some foods could make crested geckos suffer digestive problems and/or diarrhea.
