To use this crested gecko food, you can either mix it with water to make a wet food or feed it dry, depending on your gecko's preference. When storing, keep it in a cool, dry place to maintain its freshness. Make sure to check the expiration date on the package. If your gecko has any special dietary needs or health issues, it's a good idea to consult a vet. Also, always provide fresh water for your gecko along with the food.
