General Description
Christmas tree worms, belonging to the Sabellidae family under the genus Spirobranchus, are fascinating tubeworms that construct tubes made of a sturdy, parchment-like substance. Some species, such as Glomerula, opt for calcium carbonate tubes. They boast a distinctive crown of feeding tentacles emerging from their tubes and primarily feed on phytoplankton and zooplankton.
Aquarium Suitability
Considered reef-safe, Christmas tree worms require a well-prepared aquarist with prior experience and attentiveness to thrive in aquarium settings. They have a peaceful temperament but may need targeted feeding with a plankton mix to ensure adequate nutrition and prevent starvation.
Care and Hardiness
These tubeworms exhibit average hardiness levels but demand daily feeding in most aquariums to prevent malnourishment. They are sensitive to disturbances and may suffer if not fed regularly. Ideal water conditions include a pH range of 8.1-8.4, a temperature between 22.2-25.6°C, and a salinity level of 1.020-1.025 with a carbonate hardness (KH) between 8-12.
Reef Suitability
Christmas tree worms are considered reef-safe and make a valuable addition to reef aquariums. However, they may fall prey to predators like triggerfish, wrasses, angelfish, and butterflyfish who may harm or consume their delicate feeding crowns.
Aquarium Setup
When setting up an aquarium for Christmas tree worms, ensure a minimum tank size of 50 liters. Provide ample hiding spots and spaces for them to anchor their tubes securely. Maintaining stable water parameters and avoiding aggressive tank mates is crucial for their well-being.
Behaviour
These peaceful creatures spend most of their time filter-feeding with their elaborate crowns extended to catch plankton. They have fragile structures, making them vulnerable to disturbances and aggressive tank companions.
Feeding and Diet
Their diet primarily consists of phytoplankton and zooplankton such as Cyclops and pods. Regular target feeding with a varied plankton mix is essential for their nutrition and overall health.
Dimorphism and Habitat
While no information is provided on dimorphism, Christmas tree worms (Spirobranchus giganteus) are commonly found in the East Indian Ocean, West Indian Ocean, Australia, The Red Sea, The Gulf of Mexico, Indonesia, and various regions in the East Pacific and Central/West Pacific oceans. Their fascinating tube-building behavior and vibrant crowns make them a captivating sight in suitable aquarium environments.
