Description de l'espèce
Geographical Origin and Habitat: This species is native to the Indo-Pacific region but has been introduced to parts of the Western Atlantic and Caribbean. It anchors to coral reefs, sandy lagoons, and rocky substrates.
Taxonomy: Classified within the class Polychaeta, order Sabellida, and family Sabellidae. It constructs a flexible, leathery tube made of fine sand, mud particles, and mucus secreted by the worm.
Social Behavior: Sessile and non-aggressive. Extremely sensitive to light changes and water vibrations. It immediately retracts its feathery crown into the protective tube at the slightest sign of threat.
Coloration and Sexual Dimorphism: The branchial crown (radioles) displays beautiful banding patterns in combinations of brown, white, purple, orange, and cream. There is no visible sexual dimorphism in this species.
Soins, reproduction et cohabitation
Tank Setup: Requires a mature marine aquarium of at least 100 liters. Anchor the leathery tube firmly within rocky crevices or bury the lower part in a sand bed in areas with moderate, non-laminar water flow.
Diet and Feeding: Specialized filter feeder. Requires regular dosing of phytoplankton, micro-zooplankton, and liquid invertebrate foods. Without target feeding, it will slowly starve in clean water.
Water Quality: Maintain stable reef conditions: temperature 22.0 to 27.0 °C, pH 8.1 to 8.4, and salinity between 1.020 and 1.025. Very sensitive to copper treatments, which are highly toxic and lethal.
Compatibility and Tankmates: Do not house with predatory species such as butterflyfish, triggerfish, pufferfish, or certain wrasses that will nip at its delicate crown and prevent feeding.
Aquarium Breeding: Extremely rare in home aquariums. Spawns by releasing eggs and sperm into the water column. The delicate trochophore larvae are usually removed by standard aquarium filtration.
Risks and Diseases: Primary risks are copper exposure and starvation. Under extreme stress, poor water quality, or malnutrition, the worm may shed its entire crown (autotomy) or crawl out of its tube.

Profil d'invertébré
- Régime alimentaire
- Filter feeder
- The diet of Sabellastarte spectabilis typically consists of organic detritus, microalgae, or specific planktonic particles. In a home aquarium, they constantly forage along the substrate or rockwork looking for nourishment. Supplemental feeding with specialized invertebrate pellets or liquid foods may be necessary. Ensuring a varied and nutritious diet will promote vibrant colors and long-term health. Overfeeding should be avoided to maintain optimal water quality.
- Rôle écologique
- Filter feeder
- In the wild, Sabellastarte spectabilis plays a crucial role in maintaining the balance of its native ecosystem. They often act as natural cleaners, breaking down waste materials and unconsumed food. Their constant movement helps aerate the sand bed and prevent the buildup of toxic gases. By managing algae growth, they create space for slow-growing corals and sponges to thrive. A balanced aquarium ecosystem relies heavily on their diligent cleaning efforts.
- Taille adulte
- 12 cm
- Risque de saut
- No
- Sensibilité aux chocs
- High
- This invertebrate is highly sensitive to rapid fluctuations in water parameters. Sudden changes in temperature, salinity, or pH can cause severe osmotic shock and death. A slow and careful acclimation process, preferably drip acclimation, is absolutely necessary. Maintain stable aquarium conditions through regular monitoring and automated top-offs. Avoid performing excessively large water changes at once.
- Calcium et minéraux
- High
- Proper calcium levels are absolutely vital for the structural integrity and growth of this species. They continuously extract calcium carbonate from the water to build their shells, skeletons, or protective tubes. Maintaining calcium levels between 400 and 450 ppm ensures they remain healthy. It is also important to balance alkalinity and magnesium alongside calcium supplementation. Regular testing is required in heavily stocked reef aquariums.
- Mue
- Yes
- If applicable to its morphology, this invertebrate undergoes periodic molting to facilitate growth. During the molting process, the organism becomes extremely vulnerable to predation and stress. It is crucial to provide ample hiding spaces, such as caves or crevices, where they can retreat safely. Do not remove the discarded exoskeleton, as they often consume it to quickly replenish essential minerals. Disturbing them during this delicate phase can lead to fatal complications.
- Reproduction
- Oviparous
- Reproduction in the home aquarium is often challenging and rare for many invertebrate species. Most require highly specific environmental triggers, such as temperature shifts or lunar cycles. The resulting larvae usually have a prolonged planktonic stage, making them difficult to rear. Specialized food sources like phytoplankton are needed to sustain the offspring. Consequently, most specimens available in the hobby are wild-caught or professionally aquacultured.
- Compatibilité et compagnons
- Reef safe
- Compatibility varies largely based on the specific species and tank mates. They are generally peaceful but can fall prey to aggressive or predatory fish. Ensure they are housed with calm tank mates that will not nip or harass them. Research individual species requirements to avoid territorial disputes. Always monitor new additions carefully to ensure harmonious interactions.
