Common name: Black-and-Gold Chromis

General Information

The Black-and-Gold Chromis, scientifically known as Neoglyphidodon nigroris, is a striking and vibrant species popular among marine aquarists. Its bold coloration—typically featuring a dark, almost black body with a contrasting gold or yellow tail—makes it a visually appealing addition to any saltwater aquarium. Often confused with similar damselfish species, the Black-and-Gold Chromis stands out due to its distinctive color pattern.

Juveniles of Neoglyphidodon nigroris are brightly colored, typically displaying a vivid yellow body with a pair of distinctive black stripes and a black spot at the base of the pectoral fin. As they mature, their coloration changes, with the body darkening to the characteristic black color and the tail becoming gold or yellow.

In the aquarium trade, this species is appreciated for its hardiness and adaptability, making it a great choice for both novice and experienced hobbyists. It plays a role in enhancing the aesthetic appeal of marine tanks and is often used in educational settings to demonstrate marine biodiversity.

Care

Caring for the Black-and-Gold Chromis is relatively straightforward, as they are known for their resilience. They thrive in well-maintained reef aquariums with plenty of hiding places among live rock structures. A tank of at least 100 liters is recommended to provide ample space for swimming and to establish territories.

To enrich their environment, consider incorporating live rock formations and coral structures that mimic their natural habitat. These features not only provide shelter but also encourage natural behaviors and interactions.

Diet and Feeding

In the wild, Black-and-Gold Chromis are omnivorous, feeding on plankton, algae, and small invertebrates. In captivity, they should be offered a varied diet consisting of high-quality marine flakes or pellets, supplemented with frozen or live foods like brine shrimp and mysis shrimp.

Feed them small amounts two to three times a day, ensuring they consume all the food within a few minutes to prevent water quality issues. A diverse diet will help maintain their vibrant coloration and overall health.

Behavior and Compatibility

Black-and-Gold Chromis are known for their semi-aggressive temperament, particularly towards conspecifics and other damselfish. They are best kept in species-only tanks or with other robust species that can withstand their territorial nature.

While not considered reef-safe with caution, they may nip at soft corals and small invertebrates, so careful monitoring is advised when housing them in a reef setup. Their ideal companions are similarly sized fish that can hold their own in a community tank.

Habitat

Neoglyphidodon nigroris is naturally found in the Indo-Pacific region, inhabiting coral reefs and lagoons. They prefer environments with ample cover and moderate water flow, which can be replicated in captivity with well-structured aquascapes and stable water conditions.
