What can hermit crabs not eat?

Answered by Jarrod Smith

When it comes to feeding hermit crabs, it’s important to be mindful of what they can and cannot eat. While hermit crabs are omnivorous and have a wide range of dietary options, there are certain foods that should be avoided.

1. Starchy Vegetables: It’s best to avoid feeding starchy vegetables such as potatoes to hermit crabs. These vegetables are high in carbohydrates and can be difficult for hermit crabs to digest properly.

2. Iceberg Lettuce: While lettuce is generally considered safe for hermit crabs, iceberg lettuce should be avoided. It has very low nutritional value and doesn’t offer many benefits to their diet. Instead, opt for leafy greens like romaine lettuce or kale.

3. Salty, Fatty, and Sugary Snacks: Hermit crabs may be drawn to salty, fatty, or sugary snacks like pretzels, chips, and sweetened cereal, but these should be avoided. These foods can be harmful to their health and can lead to obesity or other health issues.

4. Dairy Products: Hermit crabs are not able to digest dairy products properly, so it’s best to avoid feeding them milk, cheese, or any other dairy-based foods. Stick to other sources of protein and calcium for their diet.

5. Toxic Plants: It’s important to keep hermit crabs away from any toxic plants or flowers. Some common examples include lilies, azaleas, daffodils, and tulips. Always research and ensure that the plants in their habitat are safe for them to be around.

6. Processed Foods: Avoid feeding hermit crabs any processed foods like cookies, crackers, or processed meats. These foods are often high in unhealthy additives, preservatives, and chemicals that can be harmful to hermit crabs.

7. Citrus Fruits: While some fruits can be a healthy addition to a hermit crab’s diet, it’s best to avoid citrus fruits such as oranges, lemons, or grapefruits. The high acidity content in these fruits can upset their digestive system.

When feeding your hermit crabs, it’s important to provide a balanced diet that includes a variety of fresh vegetables, fruits, and protein sources. Some safe options include leafy greens, carrots, bell peppers, apples, bananas, and shrimp or fish flakes.

Always monitor your hermit crabs’ behavior and health after introducing new foods to their diet. If you notice any adverse reactions or changes in their behavior, consult a veterinarian who specializes in exotic pets. Remember, a healthy diet is crucial for the overall well-being of your hermit crabs.
