Common name: Sea Cucumber

General information

The Tiger Tail Sea Cucumber, Colochirus crassus, is a species of sea cucumber that is popular among reef aquarium hobbyists for its detritivorous diet and its ability to help keep the sand bed clean. This species is known for its striking coloration, typically a combination of brown, yellow, and white, which resembles a tiger's tail pattern, hence the name.

Care

Tiger Tail Sea Cucumbers are relatively easy to care for but require a mature aquarium with a deep sand bed and plenty of organic detritus for them to consume. They are sensitive to changes in water quality, so stable conditions and regular maintenance are crucial. It's important to ensure that the aquarium does not have aggressive fish or invertebrates that might harm them.

Reproduction

In the wild, Colochirus crassus reproduces by releasing sperm and eggs into the water column, a process known as broadcast spawning. In the aquarium, reproduction is rare, but hobbyists can encourage it by maintaining excellent water quality and providing a stress-free environment.

Symbiosis

While not known for any specific symbiotic relationships, sea cucumbers play a vital role in the ecosystem by processing detritus and aerating the substrate, which benefits other tank inhabitants.

Habitat

Colochirus crassus is found in the Indo-Pacific region, typically dwelling in shallow waters where it burrows in sandy substrates. It is a nocturnal species that often hides during the day and becomes more active at night.
