Common name: Curryfish

General information

The Sea Cucumber, commonly known as Lollyfish or Greenfish, is a species of marine invertebrate belonging to the family Stichopodidae. Stichopus vastus is known for its significant role in the ecosystem as a detritivore, consuming organic matter and recycling nutrients within the reef environment.

These sea cucumbers have a leathery skin and an elongated body. They are usually greenish to brown in color, which helps them blend into their surroundings. They are capable of evisceration, where they expel their internal organs as a defense mechanism, which can then regenerate.

Care

Stichopus vastus is not commonly kept in home aquariums due to its large size and specialized dietary needs. However, for advanced hobbyists with large systems, they can be a unique addition. They require a sand bed for foraging and a mature system with ample organic detritus to thrive.

Reproduction

Sea cucumbers like Stichopus vastus reproduce both sexually and asexually. In the wild, they often spawn by releasing eggs and sperm into the water column. In captivity, breeding is rare but possible in well-established systems.

Symbiosis

While not known for specific symbiotic relationships like clownfish and anemones, sea cucumbers play a crucial role in the ecosystem by housing microorganisms in their gut which help in breaking down detritus.

Habitat

Stichopus vastus is found in the Indo-Pacific region, from the Red Sea to the waters of Hawaii. They inhabit various reef environments, often seen on sandy bottoms or seagrass beds.
