Common name: Hawaiian Yellow Anthias

General Information

The Hawaiian Yellow Anthias (Odontanthias fuscipinnis) is a stunning and relatively rare species in the aquarium trade, prized for its vibrant coloration and graceful swimming patterns. Native to the deeper waters of the Hawaiian Islands and Johnston Atoll, this anthias is a deepwater gem that captivates aquarists with its striking yellow fins and pinkish-orange body. Its rarity and beauty make it a sought-after addition to advanced reef aquariums.

This species is not commonly encountered in the wild due to its deepwater habitat, typically found at depths of 60 to 200 meters. As a result, specimens available in the trade are often collected by specialized divers using advanced techniques. Its unique appearance and rarity make it a centerpiece fish for dedicated hobbyists.

Care

Caring for the Hawaiian Yellow Anthias requires a well-established aquarium with pristine water quality and stable parameters. Due to its deepwater origins, it thrives in dimly lit tanks or setups with subdued lighting. Providing plenty of hiding spots with live rock and caves is essential to mimic its natural habitat and reduce stress.

This species is best suited for larger aquariums, as it appreciates ample swimming space. A tank volume of at least 300 liters is recommended. Maintaining stable water conditions and a peaceful tank environment is crucial for its well-being. It is sensitive to sudden changes in water quality, so regular maintenance and monitoring are key.

Diet and Feeding

In the wild, the Hawaiian Yellow Anthias primarily feeds on zooplankton. In captivity, it requires a varied diet to meet its nutritional needs. Offer a mix of high-quality frozen foods such as mysis shrimp, brine shrimp, and finely chopped seafood. Enriched foods and marine-based pellets can also be included to ensure a balanced diet.

Feed this species two to three times daily in small portions, as it has a high metabolism. Providing frequent, smaller meals helps replicate its natural feeding behavior and keeps it healthy and active.

Behavior and Compatibility

The Hawaiian Yellow Anthias is a peaceful species, making it a suitable addition to community reef tanks. It is generally shy and may take some time to acclimate to its new environment. Once comfortable, it will display its graceful swimming behavior and vibrant coloration.

This species is best kept in small groups or as a single specimen. If housed in groups, ensure a harem structure with one male and several females to mimic their natural social hierarchy. Avoid keeping multiple males together, as this can lead to aggression.

The Hawaiian Yellow Anthias is reef-safe and will not harm corals or invertebrates. It coexists well with other peaceful fish species but should not be housed with aggressive or overly boisterous tank mates that may outcompete it for food or cause stress.

Reproduction

Like many anthias species, the Hawaiian Yellow Anthias exhibits protogynous hermaphroditism, meaning individuals are born female and can transition to male if needed. Breeding in captivity is rare due to the challenges of replicating its deepwater environment and social structure. However, in the wild, males establish harems and court females through elaborate displays.

Captive breeding efforts for this species are still in their infancy, and successful rearing of fry has not been widely documented. Hobbyists interested in breeding this species should be prepared for significant challenges and invest in specialized setups.

Health and Common Issues

The Hawaiian Yellow Anthias is a delicate species that requires careful attention to its health and environment. It is susceptible to stress-related illnesses, such as marine ich and bacterial infections, particularly if water quality is not maintained. Quarantining new specimens and providing a stress-free environment can help prevent health issues.

When selecting a Hawaiian Yellow Anthias, look for active individuals with vibrant coloration and no visible signs of disease. Avoid fish that appear lethargic, have torn fins, or show signs of rapid breathing.

Maintaining a stable environment with consistent water parameters, high oxygen levels, and a varied diet is essential for keeping this species healthy. Regular observation and prompt action at the first sign of illness can help ensure its longevity in captivity.

Habitat

The Hawaiian Yellow Anthias is native to the deep reefs of the Hawaiian Islands and Johnston Atoll, where it inhabits rocky outcrops and ledges. These areas are characterized by low light levels, cooler temperatures, and moderate water flow. Replicating these conditions in captivity is important for its well-being.

Providing a dimly lit aquarium with plenty of live rock and hiding spots helps mimic its natural habitat. Moderate water flow and stable water conditions are also essential to replicate the gentle currents of its deepwater environment.
