Common name: Nose Sea Cucumber

General Information

The Nose Sea Cucumber, scientifically known as Stichopus naso, is a unique and intriguing species found in the marine aquarium trade. Known for its elongated body and distinctive nose-like protrusion, this sea cucumber plays an important role in the ecosystem as a detritivore, helping to clean the substrate by consuming detritus and organic matter. Its unique appearance and ecological role make it a fascinating addition to a well-established marine aquarium.

While not as commonly seen as some other marine species, the Nose Sea Cucumber is appreciated by hobbyists for its ability to contribute to the health of the aquarium environment. Its presence can aid in maintaining a clean and balanced ecosystem, making it a valuable asset for those interested in naturalistic setups.

Care

Caring for the Nose Sea Cucumber requires attention to water quality and substrate conditions. This species thrives in aquariums with a sandy substrate where it can burrow and feed. It is essential to maintain stable water parameters and avoid sudden changes, as sea cucumbers can be sensitive to fluctuations.

A well-established tank with plenty of live rock and a mature sand bed is ideal for this species. Providing a varied diet that includes detritus, microalgae, and specially formulated sinking pellets can support its nutritional needs and overall health.

Diet and Feeding

In the wild, the Nose Sea Cucumber feeds primarily on detritus, organic matter, and microalgae found within the substrate. In captivity, replicating this diet is crucial. Offering a mix of sinking pellets, detritus, and supplemental microalgae will ensure it receives the necessary nutrients. Feeding should be done sparingly, as overfeeding can lead to poor water quality.

Behavior and Compatibility

The Nose Sea Cucumber is a peaceful and non-aggressive species, making it suitable for community tanks. It poses no threat to other tank inhabitants and can coexist with a variety of reef-safe fish and invertebrates. Its slow-moving nature and detritivorous diet mean it will spend much of its time sifting through the substrate.

Care should be taken to ensure that tank mates do not harass or damage the sea cucumber, as its delicate body can be easily harmed by rough handling or aggressive species.

Health and Common Issues

Nose Sea Cucumbers are generally hardy but can be susceptible to stress from poor water quality or sudden changes in tank conditions. Maintaining a stable environment with regular water changes and monitoring of water parameters is essential for their health.

Signs of stress or poor health include a loss of color, lethargy, or a refusal to feed. If these symptoms occur, check water quality and consider consulting a marine veterinarian for advice.

Habitat

Naturally found in the Indo-Pacific region, the Nose Sea Cucumber inhabits sandy and rubble areas of coral reefs, often at depths ranging from shallow lagoons to deeper reef slopes. It prefers environments with plenty of organic material to sift through, making it well-suited to aquariums with a mature sand bed and stable conditions.
