Common name: pinkfish sea cucumber

General information

The Edible Sea Cucumber, scientifically known as Holothuria edulis, is a marine invertebrate that belongs to the family Holothuriidae. This species is often appreciated in the reef aquarium hobby for its unique appearance and beneficial role in the sand bed's maintenance. It is characterized by its elongated, cucumber-like body and leathery skin, which can vary in color from brown to black, often with lighter patches or spots.

Care

Holothuria edulis requires a spacious tank with a deep sand bed to thrive, as it burrows and sifts through the substrate, aiding in detritus breakdown and nutrient cycling. Stable water conditions and a mature aquarium are crucial for their well-being. They are sensitive to sudden changes in water parameters and should be acclimated slowly to new environments.

Reproduction

Sea cucumbers, including Holothuria edulis, reproduce both sexually and asexually. In the aquarium, sexual reproduction is rare, but they can occasionally spawn in well-established systems. Asexual reproduction, through a process called fission, can occur in some sea cucumber species, but it is not commonly observed in Holothuria edulis.

Symbiosis

While Holothuria edulis does not have notable symbiotic relationships like those seen in clownfish and anemones, it plays a crucial role in the ecosystem by processing organic matter and helping maintain water quality.

Habitat

The natural habitat of the Edible Sea Cucumber includes tropical and subtropical regions of the Indo-Pacific. They are commonly found on reef slopes and lagoons, where they feed on detritus and organic matter within the sand.
