Datasheet

General Description
The Christmas Tree Worm, scientifically known as Spirobranchus porites, was officially documented by scientists in the year 1766. This species displays an array of vibrant colors on its characteristic spiral-shaped crown, resembling a Christmas tree. Typically, only the crown is visible as the worm's body remains concealed within its host coral. When retracted, the Christmas Tree Worm makes use of its operculum, a top trap door, to seal its tube. In their habitat, multiple Christmas Tree Worms can be found, although they do not form tight colonies.

Aquarium Suitability
Considered suitable only for expert aquarists, the Christmas Tree Worm thrives in environments with stable conditions and prefers areas shaded by rocky formations rather than direct bright light. It is crucial to note that this species is highly sensitive to copper-based medications.

Care and Hardiness
Due to its delicate nature, the Christmas Tree Worm demands meticulous care in a controlled aquarium setting. Breeding within home aquariums is a rare occurrence, emphasizing the need for specialized attention to ensure its well-being.

Reef Suitability
The Christmas Tree Worm is renowned for its peaceful temperament, making it a suitable addition to reef aquariums that house compatible species. Its ability to coexist harmoniously with other marine life enhances its appeal to reef enthusiasts.

Aquarium Setup
When establishing an environment for the Christmas Tree Worm, aquarists should prioritize the presence of live rock or rubble for attachment purposes. Maintaining water conditions within the ranges of pH 8.1-8.4, specific gravity of 1.023-1.025, and alkalinity levels between 8-12 dKH is vital for the well-being of this species.

Behaviour
This species exhibits a peaceful temperament and is known to exhibit shy movements, often seeking shelter in the shadows of rocky overhangs. The Christmas Tree Worm's behavior adds to its allure and makes it an intriguing specimen to observe in a well-maintained aquarium.

Feeding and Diet
Being an omnivorous filter feeder, the Christmas Tree Worm predominantly relies on collecting microscopic food particles from the water. To supplement its diet effectively, providing liquid plankton-based foods is essential to ensure its nutritional needs are met.

Habitat and Distribution
Found primarily in tropical marine environments, the Christmas Tree Worm inhabits the calcareous substrates of coral reefs. Its distribution spans across various regions, contributing to the diversity of marine ecosystems where this captivating species can be encountered.
