Common name: Brownfish

General information

The Bumpy Sea Cucumber, scientifically known as Actinopyga echinites, is a distinctive echinoderm from the class Holothuroidea. It is easily recognized by its elongated body and the presence of numerous black-tipped papillae, which give it a characteristic bumpy texture. This species is often found in tropical reef environments and plays a crucial role in the ecosystem by processing detritus and organic matter.

Care

In the home aquarium, Actinopyga echinites requires a large tank with a deep sand bed and plenty of live rock to provide hiding places and surfaces for grazing. It is sensitive to water quality and requires stable conditions with low nitrate levels. A varied diet consisting of detritus, leftover food, and specially formulated feeds for detritivores is essential for its health.

Reproduction

Reproduction in Actinopyga echinites involves the release of eggs and sperm into the water column, where fertilization occurs. In the aquarium, breeding is rare, but hobbyists can encourage reproduction by maintaining excellent water quality and providing a stress-free environment.

Symbiosis

While not known for specific symbiotic relationships like those seen in clownfish and anemones, the Bumpy Sea Cucumber plays a symbiotic role in the reef ecosystem by cleaning the substrate and helping to maintain water quality, which benefits other tank inhabitants.

Habitat

Bumpy Sea Cucumber is commonly found in the Indo-Pacific region, from the Red Sea to the waters of Micronesia. It prefers reef flats and lagoons, typically at depths of up to 30 meters, where it can be seen meandering across the substrate.
