Common name: Pineapple Sea Cucumber

General information

The Pineapple Sea Cucumber, scientifically known as Stichopus monotuberculatus, is a unique and fascinating invertebrate that can be a great addition to a reef aquarium. This species is known for its distinctive appearance, featuring a leathery skin with an array of raised tubercles that resemble the texture of a pineapple. They are detritivores, consuming organic matter and helping to keep the substrate clean.

Care

Caring for a Pineapple Sea Cucumber requires a well-established aquarium with a deep sand bed and plenty of live rock. They are sensitive to water quality, so maintaining stable parameters and a clean environment is crucial. It's important to ensure that the aquarium has a secure lid, as sea cucumbers are known to climb and may accidentally leave the tank.

Reproduction

In the wild, Stichopus monotuberculatus reproduces by releasing gametes into the water column, a process known as broadcast spawning. In the aquarium, however, reproduction is rare and not well documented.

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

Stichopus monotuberculatus is found in the Indo-Pacific region, from the Red Sea to the waters around Australia. They typically inhabit reef slopes and lagoons, often burying themselves in the sand or hiding among the rocks during the day.
