General Description
The Southern Fan Worm, scientifically known as Sabellastarte australiensis, is a member of the tube-dwelling worm family Sabellidae. These worms construct tubes from a durable, parchment-like substance except for the Glomerula genus, which secretes a tube made of calcium carbonate. Sporting a distinctive crown of feeding tentacles, these worms primarily feed on phytoplankton and zooplankton, relying on target feeding in aquarium settings. They are not photosynthetic creatures and are susceptible to predation by certain fish and shrimp species.
Aquarium Suitability
The Southern Fan Worm is deemed suitable for aquariums with a cautious approach due to its demands and care requirements, thriving when provided with proper attention and feeding regimens.
Demands, Care, and Hardiness
With an average hardiness level, these peaceful worms prefer to have their tubes buried in the substrate, and they may require daily target feeding to prevent starvation. Maintaining stable water conditions with a pH of 8.1-8.4, a specific gravity of 1.020-1.025, and a temperature range of 22.2-25.6°C is crucial for their well-being.
Reef Suitability
The Southern Fan Worm is considered reef-safe, making it a suitable addition to reef aquariums without causing harm to the ecosystem.
Aquarium Setup
For optimal care, ensure the tubes of the Southern Fan Worm are securely buried in the aquarium substrate, providing a suitable environment for them to thrive. Additionally, regular target feeding with a mix of phytoplankton and zooplankton is recommended to meet their dietary needs.
Behaviour
Typically displaying peaceful temperament, these worms are vulnerable to disturbances from certain predatory fish and shrimp species, which may target their feeding crowns, potentially harming or killing the worm.
Feeding and Diet
Feeding the Southern Fan Worm a diet consisting of phytoplankton and zooplankton such as Cyclops and pods is essential for their nutrition and overall health.
Habitat and Distribution
The Southern Fan Worm is commonly found in the East Indian Ocean, particularly off the coast of Australia. Establishing a habitat reminiscent of their natural environment is beneficial in ensuring their well-being in an aquarium setting.
