Hard Tube Coco Worm

General information

The Hard Tube Coco Worm is either orange, pink, red, white, or yellow in color and its radioles are banded. It can grow up to 7 inches. The “crowns” of this worm is bilobed in young and spiraled in adults. The worm’s body is protected by a calcareous tube that is 1/2 inch in diameter and 5-8 inches long. This tube is used to stabilize the worm and attach it on rocks. Its radioles are used for filter-feeding. 

It is a filter-feeding invertebrate and its diet mainly consists of phytoplankton and liquid organic food.

It is native from the Indo-Pacific region.

Like most invertebrates, the Hard Tube Coco Worm does not do well if there are large swings in water parameters. It also does not tolerate any type of metal traces in the water, therefore, it should never be in contact with any copper medications.

Most invertebrates do not like large swings in water parameters and the Hard Tube Coco Worm is not an exception, so even though most hobbyists do not acclimate their cleaner crews it is suggested to do so. If you have a sump, float your cleaner crew in an area with low light to allow them to temperature acclimate first which should take about 15-20 min. Then it is best to slowly drip acclimate them to allow them to adjust to your water conditions.
