Common name: greenfish
General information
The Green Sea Cucumber, scientifically known as Stichopus chloronotus, is a striking marine invertebrate that is popular among aquarists for its unique appearance and beneficial role in the aquarium. This species is characterized by its vibrant green coloration with black-tipped papillae, which can resemble a tiger's pattern, hence the nickname 'Tiger's Tail Sea Cucumber'.
Sea cucumbers are echinoderms, closely related to sea stars and sea urchins. They play a crucial role in the ecosystem by processing detritus and organic matter, essentially cleaning the substrate and water column.

Care
Green Sea Cucumbers require a well-established aquarium with a deep sand bed and plenty of live rock to scavenge for organic matter. They are sensitive to changes in water quality, so stable conditions and regular maintenance are crucial. It's important to ensure that there are no aggressive tank mates that might harm them.
Reproduction
Reproduction in sea cucumbers can be both sexual and asexual. In the wild, Stichopus chloronotus often reproduces by releasing eggs and sperm into the water column, a process known as spawning. In the aquarium, however, reproduction is rare and not a common expectation for hobbyists.
Symbiosis
While not known for a specific symbiotic relationship like clownfish and anemones, sea cucumbers do contribute to the overall health of the reef ecosystem by cleaning and aerating the substrate, which can indirectly benefit other tank inhabitants.
Habitat
The Green Sea Cucumber is found in the Indo-Pacific region, from the Red Sea and East Africa to the central Pacific. It prefers reef environments and typically resides on the sea floor, often partially buried in the sand or hiding under rocks during the day.
