Fluker's Rivershrimp Hermit Crab Treats is made with 100% rivershrimp for a delicious and moist high-protein snack hermit crabs crave. These all-natural rivershrimp provide a convenient way to treat your crab to a tasty and nutritious snack without the mess. Hermit crabs are attracted to the smell of shrimp as soon as it's placed in their enclosure， but they only eat small amounts of food at a time， so feed them only what they can consume in a 24-hour period.
