Giant Hawaian Feather Duster

The Hawaiian Feather Duster is a fascinating addition to the reef aquarium. Considered both a feeding device and a breathing gill, the stunning crown (radiole) unfurls in all directions and sways gracefully as if keeping time with the current.

The fan-shaped crown of the Hawaiian, or Giant Feather Duster is tan or orange with brown band colorations. The radiole of some species from certain locales may be up to 7 inches in diameter, or of brighter colours.

The Hawaiian Feather Duster uses the radiole to filter out small floating organisms, which it directs toward its mouth located at the center of the crown. It protects its segmented body by secreting a parchment-like tube to cover itself. When the Hawaiian Feather Duster is disturbed, it can quickly retract its radiole into the tube. If it is severely stressed, the Hawaiian Feather Duster will discard its crown, growing it back later.

The Hawaiian Feather Duster is often positioned within the coral rubble at the base of the reef aquarium. Reef rubble is often incorporated into the parchment-like tube of the Hawaiian Feather Duster. It needs to be housed in a well-established reef system, as it is dependent upon plankton for its diet. The Hawaiian Feather Duster is very intolerant of copper-based medications.

Supplemental feeding of phytoplankton and liquid organic foods should be provided.
