About Hard Tube Coco Worm
The Hard Tube Coco Worm (Protula bispiralis) is a large feather duster that builds a white, calcium-based tube and extends a twin spiral crown in red, orange or white. It is not a coral but a filter-feeding worm that strains plankton from the water. It retracts in an instant when startled.
Hard Tube Coco Worm care at a glance
- Lighting: Any – light is not important
- Water flow: Low to moderate flow that carries food past the crown
- Placement: Wedged upright in rockwork with the crown in open water
- Feeding: Dose phytoplankton or fine liquid foods several times a week
- Care level: Moderate – needs regular feeding and stable calcium
Keep the water stable at 24 to 26°C and salinity 1.025, and feed on a regular schedule. Animals that do not rely on light decline slowly if meals are missed, so consistency matters more than quantity.
