Common name: Pilumnid crabs
Scientific name: Pilumnidae
Pilumnidae is a family of crabs known for their hairy appearance, which gives them a distinctive look among reef inhabitants. These crabs are generally small and are often found hiding in crevices or amongst the substrate. They play a role in the clean-up crew of a reef aquarium by scavenging for detritus and uneaten food. While some species are reef-safe, others may prey on small invertebrates or nip at corals, so it's important to research the specific species before adding them to a reef tank. Their behavior and compatibility can vary widely.
