General information

The Hawaiian Feather Starfish, scientifically known as Holothuria hilla, is a species of sea cucumber found in tropical waters. Despite its common name, it is not a starfish but a member of the class Holothuroidea. It is characterized by its elongated, leathery body and numerous small, feather-like tentacles around its mouth, which are used for feeding.

Care

Holothuria hilla requires a well-established reef tank with plenty of live rock and a sandy substrate to mimic its natural environment. It is a detritivore, feeding on detritus and organic matter, which makes it a beneficial addition to the cleanup crew in a reef aquarium. Care should be taken to ensure that the tank is free of aggressive fish that may harm it.

Reproduction

Sea cucumbers, including Holothuria hilla, have the ability to reproduce both sexually and asexually. In the aquarium, sexual reproduction is less common, but hobbyists may observe the release of gametes into the water column during spawning events.

Habitat

Holothuria hilla is typically found in shallow waters of the Indo-Pacific region, often hiding under rocks or within crevices during the day. At night, it emerges to feed on the surrounding detritus and organic matter.
