Do crabs eat fish?
Crabs are opportunistic eaters and will eat almost anything they can get their claws on. Unless aggressive, crabs will usually eat algae or dead animals rather than hunting live fish or invertebrates. Crabs will only go hunting if there isn't sufficient organic material to eat (such as detritus, algae, dead animals, corals, etc.) unless the crab is aggressive and prefers hunting.
