Marine Fish Perfect Health Promise
All marine fish have a Perfect Health Arrival guarantee. For the following reasons, we cannot guarantee beyond that.
A number of different reasons can affect why a marine fish does not settle into its new environment. These range from:
- Unsuitable water conditions: incorrect pH, high ammonia and nitrite levels.
- Tank bullies: some marine fish are very passive and will not mix well with more boisterous tank mates.
- Incorrect tank size: please research the fish you are buying, as some will become stressed in a tank that is too small.
If you have any problems on arrival
Please contact us straight away and we will extend your guarantee until the fish is healthy again. You must call on the arrival day to activate this.

About this fish
What is its maximum size?
The Blue Reef Chromis (Chromis cyanea) can grow to approximately 15 cm (6 inches) in length.
It is a beautiful, active schooling damselfish admired for its vibrant electric-blue body and forked tail.
Unlike many other damselfish, it is generally more peaceful and spends much of its time swimming in open water above coral reefs.
Where is its origin and where is it exported from?The Blue Reef Chromis originates from the tropical Western Atlantic Ocean, particularly the Caribbean region.
Its natural distribution includes:
Florida and the Florida Keys.
Bahamas.
Bermuda.
Gulf of Mexico.
Caribbean islands.
Central American Atlantic coastline.
Northern South America.
It inhabits coral reefs, reef slopes and rocky environments, where it forms groups and feeds on plankton in the water column.
It is collected for the marine aquarium trade primarily from Caribbean and Western Atlantic locations, including Florida, the Bahamas and other Caribbean collection areas.
Is it reef compatible?
Reef safeThe Blue Reef Chromis is considered reef safe and is an excellent choice for both mixed reef and fish-only marine aquariums.
It feeds primarily on plankton 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.
It is an excellent addition to reef aquariums, particularly when kept in a group where it can display its natural schooling behaviour.
What should I feed it?
The Blue Reef Chromis is primarily a planktivore, feeding on small crustaceans and zooplankton in the wild.
It requires a varied diet containing marine proteins and other nutritious foods.
Recommended foods include:
Frozen mysis shrimp.
Enriched brine shrimp.
Calanus.
Copepods.
Marine zooplankton preparations.
Chopped krill.
High-quality marine pellets.
Vitamin-enriched marine flakes.
Small, frequent feedings are beneficial because of its natural feeding behaviour in the water column.
Providing a varied diet will help maintain its vibrant blue coloration and overall health.
How many can I keep?
The Blue Reef Chromis is a shoaling species and is best kept in groups rather than individually.
Recommended arrangements include:
A group of at least 5–6 individuals.
Larger groups in sufficiently spacious aquariums.
Avoid keeping just two individuals, as bullying can become concentrated on the weaker fish.
Although they are generally peaceful, individuals may establish a hierarchy and occasionally chase one another.
Providing adequate swimming space and maintaining a reasonably sized group can help distribute aggression.
How compatible is it with other fish?
The Blue 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.
Avoid housing it with large predatory fish or particularly aggressive tankmates that may chase, intimidate or eat smaller individuals.
It is an excellent choice for adding movement and colour to the upper and middle sections of a marine aquarium.

Aquarium RequirementsThe Blue Reef Chromis is an active open-water swimmer and requires a spacious aquarium, particularly when kept in a group.
Recommended minimum volume: Approximately 200–300 litres for a 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 to simulate natural reef conditions.
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.
It can be sensitive to transportation stress, so careful acclimatisation and quarantine are recommended
If it does not arrive alive, you do not pay for it.
