The Hard Tube Coco Worm, also referred to as the Hard Tube Feather Duster, Protula Tubeworm, or Hard Tubeworm, displays a vibrant crown that comes in various colors such as white, yellow, orange, pink, or red. The radioles on the crown may exhibit banding or patterns. Notably, younger Hard Tube Coco Worms have bi-lobed crowns, while older individuals boast spiraled crowns.

To protect its delicate worm body, the Hard Tube Coco Worm secretes a calcareous tube, measuring about 1/2 inch in diameter and 5-8 inches in length. In response to disturbances, it can swiftly retract its crown and seal the top of the tube with an operculum. Typically, it anchors its tube in crevices on rocky reefs or in gravel along current-swept reef slopes. The worm utilizes its radioles to filter floating plankton for sustenance.

Proper care for the Hard Tube Coco Worm necessitates a well-established aquarium with a rock and gravel substrate. Calcium and the appropriate alkalinity levels are vital for its growth. This species is highly sensitive to poor water quality and should not be exposed to copper-based medications.

Due to its specific care requirements, the Hard Tube Coco Worm is classified as "Expert Only" in the aquarium trade. It will need supplementary phytoplankton and liquid organic foods to thrive successfully. As such, providing the right conditions and nutrition is essential for the well-being of this species.
