Provide a constant and varied diet. Steer clear of of marketed foods, as it has many preservatives, such as copper sulfate, which can harm the wee hermit. Hermit crabs are scavengers by nature and will eat almost anything.
Do not give them to eat anything spicy, hot or containing preservatives.
They love shrimp and silversides that are fresh, bloodworms freeze dried krill, etc., and other seafood.
Go to your local fish market and get a head of fish if you have several hermits. You can put all the crabs in a large tank or a clean large Rubbermaid storage container (clear, without a lid, or cover with large holes cut in it) toss in the fish head, and a bowl of water, and leave them there to eat for a couple of hours.The smell can be very strong, but crabs will thank you!
They also eat raw meat or if you cook give them non marinated meat
They love fresh fruit and will go bonkers over coconut shavings. Try to find a natural grow but if you can make sure to wash the fruit thoroughly before you cut.
They also eat natural peanut butter on whole wheat toast, boiled eggs, egg shells (boiled), popcorn (plain, unsalted, no butter). Don't feed your crabs the same thing twice. Mix a little. Remember, they eat what they find in nature.Remember change their food almost every day / night. Hermit crabs love to bury their uneaten food, and this can cause mold and is messy.
Avoid anything from Allium plants (onion, garlic, etc.).
