Crested geckos are omnivores, this means they will eat fruit as well as insects so should be given both. Any live food should be gut loaded (fed) before feeding to your crested gecko, this will make the insects more nutritious which will in turn help to prevent illness and disease. You can gut load your live food on a range of leafy greens and root vegetables.
Crested geckos should be fed on crickets and locusts depending on their size (the insects should be no larger than the width of your crested gecko’s head), if the crickets are too large then they will not be able to be consumed. You may also feed your crested gecko mealworms and waxworms but feed these sparingly as they are fatty. Calcium powder should be added to the bugs that are
fed to help with calcium intake.
You can also feed a range of fruits to your crested gecko. These include: berries (strawberries, blueberries, raspberries), banana, watermelon, apricots, mango and cantaloupe. There is a lot more they can eat but always check before feeding new things as some things may be toxic to them and make them unwell.
You primarily want to offer fruit or vegetables daily and insects 2-3 times weekly. Place all food into a ceramic bowl as some substrates, if ingested, can cause impaction.
You may also feed Repashy Super Foods, a powder supplement for crested geckos, that helps to ensure they are receiving the correct nutrition.
Water should always be supplied but some crested geckos prefer to drink from the water droplets on the leaves. Water must be changed daily.
