Artbeschreibung
Geographical Origin and Habitat: A marine species; the enclosure should provide stability, oxygenation, space and shelter consistent with its behaviour without turning one habitat description into a mandatory recipe.
Taxonomy and Morphology: The accepted scientific name is Halichoeres chrysus; the verified classification records genus Halichoeres, family Labridae, order Perciformes. Historical names remain searchable as synonyms rather than separate species.
Social Behavior: Yellow coris wrasse is normally kept as a single individual and does not require conspecifics. The minimum reference is one individual; sex, maturity and available space can require a more conservative composition. Observe access to food, resting behaviour, chasing and use of shelter. Isolation, persistent competition or aggression means the number, composition or environment needs to be corrected.
Coloration and Sexual Dimorphism: Colour and shape can vary with age, sex, physiological state and environmental conditions. Identification and sexing require recognized species-level characters; one appearance or photograph is not enough.
Pflege, Zucht und Mitbewohner
Aquarium Setup: Yellow coris wrasse needs an aquarium of at least 250 litres, sized for adult body size and a minimum group of one individual. Filtration, shelter and swimming room must match the species and the actual number kept. Volume alone does not make an enclosure suitable: tank shape and length, usable area, oxygenation and the ability to separate territories must reflect adult behaviour.
Diet and Feeding: The recorded diet is omnivorous. Offer appropriately sized foods varied within that category, and adjust quantity and frequency from actual intake, body condition and leftovers. One food or a fixed schedule is not suitable for every age and situation.
Water Quality: Maintain stable, well-oxygenated water appropriate to a marine species; the card's reference values are 24–27 °C, pH 8.1–8.4. Verify conditions with reliable tests and size maintenance and filtration to the actual load. Ranges are not automatic thresholds for treatment or rapid chemical correction.
Compatibility and Cohabitation: The cohabitation profile is reef-safe with caution, with a generally peaceful temperament. Keep at least one individual; tankmates, stocking density and decor must allow escape, rest and feeding without excessive competition. Watch interactions especially during feeding, maturity and breeding. Persistent chasing, injury or exclusion from food requires a change in stocking or layout, or separation of the animals.
Aquarium Breeding: The recorded reproductive profile is “oviparity”. Breeding should be attempted only with healthy adults, separation capacity and a plan for eggs or young. Do not treat unverified triggers, sex ratios or hatch times as universal for this species.
Risks and Diseases: Prevent problems through quarantine of new arrivals, stable water, appropriate feeding and daily observation. Similar signs can have different causes, so check parameters, history and diagnosis before medication. Follow the product label and qualified aquatic-veterinary advice; there is no universal reduced dose for a species or family.

Fischprofil
- Temperament
- Peaceful
- Yellow coris wrasse has a generally peaceful temperament. Insufficient space, an unsuitable social ratio or incompatible tankmates can substantially change observed behaviour.
- Diät
- Omnivore
- In the wild, their diet consists almost entirely of small crustaceans, mollusks, and various pests found on the reef. In captivity, they must be provided with a varied, high-protein diet consisting of mysis shrimp, vitamin-enriched brine shrimp, and finely chopped seafood. Once acclimated, they are generally not picky and will eagerly accept high-quality marine flakes and sinking micro-pellets. Providing a diverse diet is crucial for maintaining their brilliant yellow coloration and robust immune system. Their natural hunting instincts make them an invaluable biological control for many common reef pests.
- Lebenserwartung
- 5-10 years
- Erwachsenengröße
- 12 cm
- Geschlechterverhältnis
- Solitary
- Yellow coris wrasse is normally kept as a single individual and does not require conspecifics. The reference minimum is one individual and must not be read as permission to overcrowd the aquarium.
- Fütterungsfrequenz
- Twice daily
- Due to their high energy levels and rapid metabolism, the Yellow Wrasse should be fed two to three times a day. Offering smaller, more frequent meals mimics their natural continuous foraging behavior and ensures they maintain a healthy weight. They are fast, bold eaters that will eagerly dart into the water column to snatch food before it sinks to the bottom. Care should be taken to ensure that slower or more timid tank mates receive adequate food during feeding time. Overfeeding should be avoided to prevent degrading the water quality in the aquarium.
- Bioload
- Medium
- The Yellow Wrasse produces a moderate bioload that is proportional to its highly active swimming behavior and frequent feeding requirements. As a carnivore with a fast metabolism, it processes food quickly, resulting in steady waste production throughout the day. An efficient protein skimmer and a robust biological filter are essential to keep the water pristine and prevent nitrate accumulation. Because they are messy eaters, uneaten food can easily become trapped in the rockwork, necessitating regular tank maintenance and siphoning. Overall, their bioload is manageable in most standard reef setups provided routine husbandry is maintained.
- Fluss
- Strong
- They prefer an aquarium with moderate to strong water flow, which replicates the dynamic currents of their natural reef environment. Strong circulation is essential to provide the high oxygen levels these active swimmers require to thrive. The flow also helps keep detritus suspended, allowing the filtration system to process it effectively and keep the water clear. While they enjoy swimming against the current, they also need access to calmer areas within the rockwork where they can rest. Adequate surface agitation is crucial for promoting the necessary gas exchange for optimal health.
- Sprungrisiko
- No
- Reproduktion
- Oviparous
- Breeding the Yellow Wrasse in a typical home aquarium is exceptionally rare and virtually impossible for the average hobbyist. They are pelagic spawners that require a massive vertical water column to perform their courtship dances and release their gametes. The fertilized eggs become buoyant and drift in the ocean currents as part of the plankton before hatching into microscopic larvae. The specific dietary needs of these larvae and the required environmental cues are beyond current captive capabilities. Consequently, all Yellow Wrasses available in the trade are ethically sourced from wild populations.
- Kompatibilität & Tankkameraden
- Reef safe with caution
- The cohabitation profile is reef-safe with caution, with a generally peaceful temperament. Keep at least one individual; tankmates, stocking density and decor must allow escape, rest and feeding without excessive competition. Watch interactions especially during feeding, maturity and breeding. Persistent chasing, injury or exclusion from food requires a change in stocking or layout, or separation of the animals.
- Tankfüllstand
- Middle/Bottom
- They are highly active fish that utilize the entire aquarium, constantly darting in and out of the rockwork to hunt for pests. A soft, fine sand bed of at least two to three inches deep is a non-negotiable requirement for this species. They sleep completely buried in the sand every night and will instantly dive into it if they feel frightened or threatened. Tanks with bare bottoms or coarse crushed coral are completely inappropriate and will cause severe stress and physical injury. They need a balance of complex rockwork for hunting and open space for swimming.
