Neoglyphidodon nigroris Care Guide
Neoglyphidodon nigroris is an Indo-Pacific damselfish whose bright striped juveniles darken with age and become territorial adults.
Overview
Neoglyphidodon nigroris is a marine damselfish of the family Pomacentridae, described by Cuvier in 1830 and commonly known as the black-and-gold chromis or Behn's damsel. Juveniles are yellow with two longitudinal black stripes and a black spot at the base of the pectoral fin, while adults are much darker. According to FishBase, the species occurs across the Indo-West Pacific.
Taxonomy
- Family: Pomacentridae
- Genus: Neoglyphidodon
- Scientific name: Neoglyphidodon nigroris
- Author: Cuvier, 1830
Habitat
The species is reef-associated and non-migratory, inhabiting coral-rich areas of lagoons and seaward reefs at depths of about 2 to 23 metres. FishBase records its range across the Indo-West Pacific, from the Andaman Sea and Malayan Archipelago to Indonesia, the Philippines, Taiwan, the Ryukyu Islands, Palau, New Guinea, the Solomon Islands, Vanuatu and northern Australia. Two regional colour forms are recognised.
Tank requirements
- Minimum tank volume: 200 L
- Temperature: 24-26 °C (75-79 °F)
- pH: 8.1-8.4
- Adult size: 11-13 cm
- Lifespan: 5-10 years
- Substrate: sand with rockwork providing crevices
Diet
Neoglyphidodon nigroris is an omnivore. In the wild it feeds on algae, crustaceans, and pelagic tunicates and salps. In aquaria it accepts a mixed diet of prepared marine foods alongside algae-based feeds, offered about twice daily.
Compatibility
The species is diurnal and usually solitary, with territorial behaviour that intensifies as it matures. Adults chase smaller fishes and retreat into crevices to avoid larger ones. Robust tankmates such as tangs, wrasses and triggers (with caution) are more suitable than slow or shy fishes and other small damsels housed in confined tanks.
Breeding
The species is oviparous and forms distinct pairs during breeding. Eggs are demersal and adhere to the substrate, and the male guards and aerates them until they hatch.
Conservation status
IUCN Red List: Least Concern, assessed in September 2021.
