If a predator attacks, the Dwarf Zebra Hermit Crab can back into its shell and use the large claw to block the entrance to its shell.

Aquarium Care

How to successfully keep Dwarf Zebra Hermit Crab in the home aquarium.

The Dwarf Zebra Hermit Crab is a valuable addition to an aquarium because it eats many kinds of algae, including red slime algae (cyanobacteria), and sifts the sand, as well. This species should only be added to mature marine aquariums where a plentiful source of marine algae is present.

The Dwarf Zebra Hermit Crab makes an excellent addition to any marine community or reef aquarium, as it will eat most any marine algae and will not cause any harm to even the most sensitive fish, coral or invert species.

The small adult size of this species also makes them an excellent addition to nano-aquariums. Overall a very easy species to keep and very rewarding and beneficial as well.

Feeding & Nutrition

How to feed and provide proper nutrition for Dwarf Zebra Hermit Crab.
