What do sea hermit crabs eat?

According to The Hermit Crab Patch, hermit crabs are omnivorous scavengers. In captivity, they can be fed a range of plant and meat varieties, but the size of their meals needs to be properly adjusted to their size, according to PawNation.

Mango, pawpaw, fresh or dried coconut, bananas, apples, pineapple, strawberries, melons, grapes and raisins are suitable food for hermit crabs. They can also be fed vegetables such as leafy green lettuce varieties, spinach, watercress, carrots and broccoli. Apart from fruit, the meals of hermit crabs can include freeze-dried shrimp, poultry, fish-food flakes and strips of bark and leaves from deciduous trees.
