Dwarf Red Tip Hermit Crab (Clibanarius diguetti) Care
The Red Tip Hermit Crab, Clibanarius diguetti, is also known as the Mexican Red-leg Hermit and the Bluespotted Hermit. These crabs come from the Western Atlantic Ocean, including the Gulf of Mexico. They have red legs and a red face; both claws are the same size.
These crabs are omnivores and highly desirable in reef tanks because they will eat unwanted algae and any leftover meaty foods left in the tank by other tank-mates. They can reach most cracks and crevices and will not both fish, corals nor other invertebrates. You should not need to feed them unless you have very little algae in the tank.
They require an aquarium of at least 1 gallon; in fact, it is recommended to have at least one hermit crab for every 1 gallon of aquarium water. They are peaceful to other tank-mates EXCEPT to potential snails that have a shell that the hermit crab wants – they will kill snails for their shells.
