General information

The Sandfish Sea Cucumber, scientifically known as Stichopus horrens, is a tropical marine invertebrate found in reef environments. It is known for its elongated, leathery body and its ability to sift through sand, which gives it its common name. This species plays a crucial role in the ecosystem by consuming detritus and helping to maintain the cleanliness and balance of the substrate.

Care

Stichopus horrens is a detritivore and requires a sandy substrate in the aquarium to thrive. It is important to have a mature system with a deep sand bed to provide an adequate food source. These sea cucumbers are sensitive to water quality, so stable conditions and regular maintenance are essential. They are not aggressive and can be kept with a wide variety of tank mates.

Reproduction

In the wild, Stichopus horrens reproduces by releasing eggs and sperm into the water column, a process known as broadcast spawning. In the aquarium, breeding is rare, but with optimal conditions, it is possible to observe spawning behavior.

Habitat

The Sandfish Sea Cucumber is commonly found in the Indo-Pacific region, from the Red Sea to the waters around Australia. It prefers sandy bottoms and seagrass beds, where it can burrow and feed. In the aquarium, it requires a similar environment to mimic its natural habitat.
