Cocoworm: Colored - Protula magnifica

The Hard Tube Coco Worm, Protula magnifica, also known as the Hard Tube Feather Duster, Protula Tubeworm, or Hard Tubeworm, features a varied colored feathery crown protruding from a calcareous tube.

The tube will attach to sandy or rocky substrate and the radiole will protrude filtering the water column for food. This species is incredibly intolerant of poor water quality and should not be kept with predatory fish, urchins, or serpent starfish.

This tubeworm is an excellent addition to any reef tank as it is relatively easy to care for and adds a splash of color and diversity to most tanks. 

The Hard Tube Coco Worm, also known as the Hard Tube Feather Duster, Protula Tubeworm, or Hard Tubeworm, has a crown that can be white, yellow, orange, pink, or red. The radioles may be banded or patterned. Younger Hard Tube Coco Worms have bi-lobed crowns, while the crowns of older individuals are spiraled.

The Hard Tube Coco Worm secretes a calcareous tube, approximately 1/2 inch in diameter and 5-8 inches long, to house its vulnerable worm body. When disturbed, it can quickly retract its crown and close its operculum to shut the top of its tube. It usually anchors its tube in a crevice of the rocky reef or in the gravel along current-swept reef slopes. It uses the radioles to filter out floating plankton.

The aquarium for the Hard Tube Coco Worm should be well-established and contain a rock and gravel substrate. The Hard Tube Coco Worm requires calcium and the proper alkalinity to grow. It is extremely intolerant of poor water quality and copper-based medications.
