If you have just started keeping a crested gecko, you may have heard that you can feed them fruit, but exactly which fruits are safe? How should they be fed? I have over 10 years of experience keeping crested geckos, and I have seen too many owners cause their pets to suffer from diarrhea or even poisoning by feeding the wrong fruits. This article will answer your questions directly and help you avoid common mistakes.
Why Do Crested Geckos Need Fruit?
Crested geckos are omnivores that eat fruits, nectar, and insects in the wild. Fruits provide vitamins, hydration, and natural sugars, which can supplement nutrients that might be lacking in commercial diets. However, this does not mean all fruits are suitable. Some owners blindly feed fruits thinking they are healthy, resulting in excessive strain on their pets’ kidneys.
I remember when I first started keeping them, because I fed too much banana, my gecko’s droppings became runny. It only improved later after I adjusted the feeding frequency. Fruit should be treated as a supplement or treat, not a staple diet.
Key Nutrients in Fruit
Vitamin C, potassium, and fiber are beneficial to crested geckos, but the sugar content should not be too high. For example, pectin in apples aids digestion, and antioxidants in berries boost the immune system. However, these must all be fed in moderation.
Safe Fruit List and Preparation Methods
Based on my personal experience, the following is a list of safe fruits that are popular with geckos. Before feeding, be sure to peel, remove seeds, and cut them into small pieces, about half the size of the gecko’s head.
| Fruit Name | Recommended Feeding Frequency | Preparation Notes |
|---|---|---|
| Banana | 1-2 times per week | Choose fully ripe ones, peel and cut into small pieces; avoid overfeeding to prevent constipation. |
| Apple | 1 time per week | Peel and core, slice thinly or dice. |
| Strawberry | 1 time every two weeks | Wash and remove the stem, cut into small pieces. Portion size must be controlled due to higher sugar content. |
| Blueberry | 1 time per week | Fresh or thawed from frozen are both fine, serve whole or cut in half. |
| Mango | 1-2 times per month | Peel and pit, cut into small pieces. Some individuals may be allergic, so observation is needed. |
| Papaya | 1 time per week | Peel and seed, cut into small pieces. Contains enzymes that aid digestion. |
It is recommended to offer fresh fruit and avoid canned or processed products, as the added sugars and preservatives in them are harmful to geckos. I usually prepare a small amount at a time and put the rest in the refrigerator, but it must be brought back to room temperature before feeding; geckos do not like food that is too cold.
Tip: Making a mixed fruit puree (such as banana mixed with blueberry) can increase the gecko’s appetite, but remember never to add honey or sugar. Use a high-speed blender or baby food maker to blend it until the texture is similar to baby food.
Dangerous Fruits That Are Absolutely Forbidden
Some fruits are nothing short of poison to crested geckos, which beginners often overlook. I once saw someone feed avocado, which caused the gecko to vomit and be rushed to the vet.
- Avocado: Contains persin, which is fatal to reptiles and must absolutely never be fed.
- Citrus (Oranges, Lemons): Too acidic; will irritate the digestive tract and cause diarrhea.
- Grapes and Raisins: Although toxic to cats and dogs, the risk to geckos is still unclear, but it is recommended to avoid them to be safe.
- Pits or Seeds: Apple seeds and similar items contain cyanide; even trace amounts can be harmful and must be removed.
Another common mistake: feeding overripe or moldy fruit. Mycotoxins can damage the liver. I once accidentally fed a slightly moldy strawberry, and my gecko was lethargic for days; since then, I only feed completely fresh fruit.
Warning: If the gecko shows symptoms of lethargy, diarrhea, or anorexia after eating fruit, stop feeding immediately and consult a veterinarian. Reptiles have slow metabolisms, and symptoms of poisoning may be delayed.
Proper Steps for Feeding Fruit
Feeding fruit isn’t just tossing it casually into the enclosure. The following are specific steps to mimic wild foraging behavior:
Step 1: Selection and Preparation.
Pick a fruit from the safe list and wash it thoroughly. Peel and seed it, using a ceramic knife to cut it into small pieces (metal knives may leave a metallic taste). Keep the size to about 0.5 cm square.
Step 2: Portion Control.
Do not feed more than the volume of the gecko’s head at one time. For an adult crested gecko, a small teaspoon per serving is enough; for juveniles, this should be halved.
Step 3: Feeding Time.
Choose to feed in the evening or at night, as crested geckos are nocturnal. Feeding times for fruits and insects should be staggered—for example, fruit on Monday and crickets on Tuesday—to avoid nutritional imbalances.
Step 4: Cleaning Up Leftovers.
Uneaten fruit should be removed within 2 hours after feeding to prevent rotting and bacterial growth. It is recommended to use small tweezers to clean it up, avoiding direct hand contact to keep from startling the gecko.
Regarding frequency, I recommend feeding fruit 1-2 times a week, relying primarily on commercial diets and insects the rest of the time. Overfeeding fruit will lead to obesity and calcium deficiency, as fruits typically present a “high phosphorus, low calcium” profile.
Here is a case study: A friend of mine fed strawberries every day, and as a result, the gecko became obese and inactive. It only regained its vitality after adjustments were made. Balance is the key to keeping them.
Frequently Asked Questions
Not recommended. Eating fruit every day leads to excessive sugar intake, which may cause obesity or metabolic issues. I only feed 1-2 times a week, using it as a supplemental treat. The staple diet should still consist mainly of high-protein insects and formulated diets to maintain a proper calcium-to-phosphorus balance.
Please suspend all fruit feeding first, switch back to solely their formulated diet, and provide plenty of water. Diarrhea could be caused by the fruit being too sweet, the portion being too large, or individual intolerance. Observe for 24 hours; if symptoms persist, it might be an infection or poisoning, and you need to seek help from a reptile veterinarian. I encountered this once before due to a mango allergy, and things returned to normal after switching to blueberries.
Observe the appearance and smell. The fruit should be brightly colored, with no bruises or mold spots. It should have a natural fruity scent and no rancid odor. Choosing organic fruit is better as it reduces the risk of pesticide residue. I usually buy and use it immediately to avoid storing it for too long. If the fruit discolors or weeps liquid after cutting, do not feed it anymore.
Yes, but you must be more careful. Juveniles have weaker digestive systems, and the fruit needs to be cut much finer, or even pureed. The frequency should be reduced to once every two weeks, in very tiny amounts. The focus should be on prioritizing protein to promote growth, with fruit acting only as a supplement. When raising juveniles, I only feed mashed banana, giving just the size of a mung bean each time.
It is best to feed them separately. Mixed feeding may cause the gecko to become a picky eater, eating only the fruit and ignoring the insects, thereby leading to insufficient protein intake. It is recommended to feed them separately, such as offering fruit first in the evening, and feeding crickets a few hours later. This not only simulates a natural foraging environment but also makes it easier to monitor their food intake.
In short, feeding fruit to crested geckos requires scientific knowledge and careful observation. Start with the safe list, offer small, diverse amounts, and closely observe your pet’s reactions. If you have any doubts, it is always better to be conservative than to take a risk. Keeping reptile pets is a science, but seeing them healthy and active makes all the effort worthwhile.
