About this fish

 
What is its maximum size?
The Barrier Reef Chromis (Chromis nitida) can grow to approximately 7–9 cm (3–3.5 inches) in length.
It is a small, attractive and active schooling damselfish, admired for its shimmering silver-white body, yellow upper back and distinctive dark diagonal stripe running from the eye towards the dorsal fin.
It is also known as the Yellow-back Puller or Shining Puller. 


Where is its origin and where is it exported from?The Barrier Reef Chromis originates from the Western Pacific, particularly the eastern Australian coastline.
Its natural distribution includes:
Great Barrier Reef, Australia.
Queensland.
New South Wales.
Lord Howe Island.
Surrounding Coral Sea waters.
It inhabits outer reef faces and slopes, where it forms small to large groups and feeds on planktonic crustaceans, fish eggs and algae.
It is occasionally exported for the marine aquarium trade, primarily from Australia. Availability is relatively limited compared with more commonly traded Chromis species. 


Is it reef compatible?
Reef safeThe Barrier Reef Chromis is considered reef safe and is an excellent choice for established reef aquariums.
It is a plankton-feeding species and does not normally nip at corals or ornamental invertebrates.
Potential compatibility includes:
LPS corals: Generally safe.
SPS corals: Generally safe.
Soft corals: Generally safe.
Zoanthids: Generally safe.
Clams: Generally safe.
Shrimps and ornamental invertebrates: Generally safe.
Its peaceful temperament makes it suitable for mixed reef aquariums, although occasional chasing and hierarchy behaviour can occur within groups. 


What should I feed it?The Barrier Reef Chromis is an omnivore and planktivore, feeding naturally on zooplankton, small crustaceans and algae.
It readily accepts a variety of aquarium foods.
Recommended foods include:
Frozen mysis shrimp.
Enriched brine shrimp.
Copepods.
Calanus.
Marine zooplankton preparations.
High-quality marine flakes.
Small marine pellets.
Spirulina-based foods.
Finely chopped marine seafood.
A varied diet containing both meaty and algae-based foods will help maintain its health and vibrant coloration.
Several small feedings throughout the day are beneficial because of its active feeding behaviour in the water column. 


How many can I keep?
The Barrier Reef Chromis is a shoaling species and is best kept in groups rather than individually.
Recommended arrangements include:
A group of 5–7 individuals.
Larger groups in sufficiently spacious aquariums.
A single specimen if group housing is not practical.
Keeping them in a suitable group helps distribute aggression and encourages more natural schooling behaviour.
Avoid keeping just two or three individuals, as dominant fish may repeatedly bully weaker members of the group. 


How compatible is it with other fish?
The Barrier Reef Chromis is generally peaceful and suitable for established marine community aquariums.
It usually coexists well with a wide variety of reef-compatible fish, including:
Clownfish.
Tangs.
Anthias.
Wrasses.
Gobies.
Blennies.
Peaceful angelfish.
Other peaceful Chromis species.
It can occasionally display mild aggression towards members of its own group, particularly when kept in insufficient numbers or confined spaces.
Avoid housing it with large predatory fish or particularly aggressive tankmates that may intimidate it or prevent it from feeding properly.

Aquarium Requirements
The Barrier Reef Chromis is an active open-water swimmer and requires a spacious aquarium, particularly when kept in a group.
Recommended minimum volume: Approximately 200–250 litres for a small group, with larger aquariums preferable for larger shoals.
Aquarium type: Reef or fish-only marine aquarium.
Aquascaping: Mature live rock with caves and hiding places.
Swimming space: Large open swimming areas are essential.
Water flow: Moderate to strong circulation.
Filtration: Efficient biological filtration and effective protein skimming.
Feeding: Several small, varied plankton-rich meals daily.
This species benefits from a mature aquarium with plenty of open swimming space and suitable shelter among the live rock
