Fiddler crabs are scavengers and will eat a variety of foods. Though they will eat fish flakes, flakes are not recommended. They will eat algae wafers, sinking pellets, carnivore pellets, and specialized crab food. Avoid foods with copper, copper sulfate, ethoxyquin, and preservatives. Copper is dangerous to all inverts and can kill. Ethoxyquin has been linked to molt deformities in hermit crabs, and the same may apply to fiddler crabs. Along with commercial food, it is beneficial to supplement with natural foods. A list of foods is available below. You may supplement your crab’s diet with calcium, and treats such as freeze dried bloodworms, shrimp, krill, tubifex worms, etc.
