Spirobranchus spp. are small, tube-dwelling polychaete worms commonly known as feather duster worms. These fascinating invertebrates are prized in marine aquariums for their delicate, fan-like crowns that extend from their calcareous tubes, filtering plankton and detritus from the water.
Supplied attached to live rock, these worms contribute to the biological filtration of your reef system while adding natural movement and texture. Their feather-like radioles retract quickly when disturbed, making them an intriguing addition to any marine setup.
Care Requirements
- Lighting: Moderate lighting is sufficient, as Spirobranchus spp. do not rely on photosynthesis.
- Water Flow: Gentle to moderate water flow is ideal to deliver planktonic food particles without damaging their delicate crowns.
- Placement: Position on stable rockwork in areas with moderate flow and away from aggressive coral species that may sting or overshadow them.
- Feeding: Primarily filter feeders; supplemental feeding with phytoplankton or liquid invertebrate foods can support health, especially in nutrient-poor systems.
- Compatibility: Reef safe with adequate spacing; avoid housing with predatory fish or invertebrates that may nip at their crowns.
Additional Notes
As the exact species within the Spirobranchus genus may vary, conservative husbandry practices are recommended. Regular water quality maintenance and stable parameters will ensure longevity and health.
