Family: Pomacentridae ยท Chromis & Damselfish
Also known as: Barrier Reef Puller, Shining Chromis
The Barrier Reef Chromis is a brilliant blue-green schooling fish native to the Western Pacific, where it is most commonly encountered along Australia's Great Barrier Reef. Its body displays an iridescent blue-green sheen that is particularly vivid under reef lighting, making a school of these fish a captivating sight as they shimmer and flash in unison above the rockwork. The species is named for its strong association with the Great Barrier Reef ecosystem, where it forms large aggregations above branching coral formations.
In the wild, Barrier Reef Chromis inhabit outer reef slopes and lagoons at moderate depths, hovering in the water column to feed on passing zooplankton. They rely on the intricate branch structures of staghorn and table corals for shelter, retreating into the coral at the first sign of danger. This natural schooling behavior makes them an excellent choice for aquarists looking to recreate the dynamic movement and energy of a natural reef scene in their home aquarium.
In captivity, Barrier Reef Chromis are hardy, disease-resistant, and easy to care for, making them an ideal choice for beginner marine aquarists. They thrive in groups of five or more in tanks of at least 30 gallons. Their peaceful temperament and completely reef-safe nature allow them to coexist harmoniously with virtually any community reef fish. Like other Chromis species, they may develop a mild dominance hierarchy within the group, but this is generally less pronounced when kept in larger numbers with ample swimming space.
Barrier Reef Chromis are omnivorous planktivores that feed on zooplankton and small organisms in the wild. In captivity, they readily accept marine flakes, pellets, frozen mysis shrimp, enriched brine shrimp, and cyclops. Feed small portions two to three times daily for optimal health and coloration.
Barrier Reef Chromis are peaceful and compatible with virtually all community reef fish. They coexist well with clownfish, tangs, wrasses, gobies, blennies, and other peaceful species. They pose no threat to corals or invertebrates. Avoid housing with large aggressive species that may prey on them.
Check CompatibilityBarrier Reef Chromis are substrate spawners with male parental care. The male prepares a nest site and guards the eggs until hatching. Spawning may occur in captivity, but rearing the small pelagic larvae requires specialized live food cultures including rotifers and phytoplankton.
