Common name: Tiger Tail Sea Cucumber

General information

The Tiger Tail Sea Cucumber, scientifically known as Holothuria pervicax, is a striking and beneficial addition to any reef or fish-only aquarium. This species is known for its distinctive dark body with vibrant orange to yellow bands, resembling a tiger's tail. As a detritivore, it plays a crucial role in the ecosystem by consuming detritus, uneaten food, and waste, thus helping to maintain water quality and reduce nitrates.

Care

Tiger Tail Sea Cucumbers require a well-established aquarium with a deep sand bed and plenty of live rock to thrive. They are sensitive to changes in water parameters, so stability is key. It's important to ensure that the aquarium is free from aggressive fish or invertebrates that might harm them. They should be fed a diet that includes organic detritus and sinking foods if natural food sources are scarce.

Reproduction

In the wild, Holothuria pervicax reproduces by releasing eggs and sperm into the water column, a process known as broadcast spawning. In the aquarium, reproduction is rare, but hobbyists may occasionally observe small sea cucumbers appearing in their tanks, indicating successful reproduction.

Symbiosis

While not known for any specific symbiotic relationships, sea cucumbers like Holothuria pervicax contribute to the overall health of the reef ecosystem by providing cleaning services and nutrient cycling.

Habitat

Holothuria pervicax is found in the Indo-Pacific region, typically dwelling in sandy areas and seagrass beds of lagoons and reef flats. They are often seen partially buried in the substrate with only their feeding tentacles exposed.
