If living in the wild, hermit crabs eat a wide variety of foods made from decaying wood, fallen fruits, leaves and grasses, and items that are washed ashore. These pets are omnivorous, which means that they eat both meat and vegetables. They may be very picky when picking up the shells that they will use as a home, but they are not at all picky about the food they eat. They locate food in two ways: by smelling the food and by watching other crabs eat the food.

• You can buy hermit crab food at most pet stores that sell land hermit crabs. These commercially prepared foods are suitable for your crabs’ diet. However, your hermit crab can also live on the food we eat.
• Your little pets will eat just about anything you serve them. But these foods are suitable additions to your pet’s diet: apples, chicken, bananas, carrots, bread, corn, cornmeal, crackers, cereals, coconut, grapes, fish, lettuce, and shrimp in the shell. If serving meat, make sure it is cooked through and does not contain butter or sauce.
• If the pet store near your area does not sell specialty foods, you can also buy granulated turtle food. Find pellets that are appropriate for the size of your hermits to prevent them from choking on large pellets.
• You don’t need to worry about how much you feed your pets. You can provide as much food that your land hermit crab can and is willing to eat. But don’t forget to remove uneaten fresh food from your crab the next day to prevent spoiling and attracting insects.
• These fascinating creatures can also go long periods of time without eating anything. Don’t worry if your hermies don’t eat for a period of time. Keep offering food and they will eat when they feel ready to eat again.
• How much to feed a hermit crab? How much of fresh food and commercially prepared food? The key here is to balance it. Never make your hermit crabs eat too much commercially prepared food. Always alternate with fresh food.
• Always have clean, fresh water in his cage. Keep the water in a shallow dish, or a shallow shell is preferred. These little animals can drown in the water dish if they can’t get out of the dish, so make sure you have stone or wooden steps to climb. The shells in your tank make the best food and water dishes, as they can also be a good source of calcium for crabs. Another good source of calcium for hermit crabs is cuttlefish. Never use metal plates for your crab because metal can be poisonous to them.
• You can do this test on how much to feed a hermit crab. Offer two or three kinds of food at the same time. Your crab will eat the candy that smells stronger and better than the others, and this is the food that it likes the most. But of course, offer them a variety of foods and not just the same food all the time.
