Chromis

Chromis verater

Jordan & Metz, 1912

Threespot Chromis

Likely Reef Tank Suitable

Likely Fish-Only Tank Suitable

Range: Central Pacific Ocean: Hawaiian and Johnston Islands.

Size: 7 inches (17 cm)

Natural Environment: Inhabits rocky bottom areas around caves at depths between 20 to about 500 feet (6 – 150 m), yet usually seen at slightly over 100 feet (30 m) where it feeds mainly on planktonic crustaceans (copepods, mysis, and shrimp larvae), fish eggs, and algae.

General Husbandry: Very rarely seen in the trade due to its drab appearance and that its one of the largest in this genus. Has a dark grey body with three white spots at the rear of the body, one above, one below and one on the base of the tail. Sometimes, the entire body turns a silvery grey.

Quite hardy, peaceful, and better maintained in small groups of at least five to seven members. Should be given wide-open swimming areas, yet an aquarium having caves and ledges to take shelter. This is also mostly a low light/deep water species, therefore a dimly lit aquarium would suit this species much more than a brightly lit reef aquarium.

As to diet, will eat most regular aquarium foods, e.g., live fortified brine shrimp and/or finely chopped various frozen or fresh meaty foods such as mysis, squid, fish flesh, shrimp, clam, etc., and plant material, e.g., flake foods, especially those containing Spirulina and should be offered several times daily.

Taxonomy:

    Order: Perciformes

    Suborder: Labroidei

    Family: Pomacentridae

    Subfamily: Chrominae

    Genus: Chromis

FYI: Even though quite passive and will ignore other fish in the aquarium, larger aquariums, e.g., 75 gallons and above for this species provide far more openness for small shoals to ‘peacefully’ coexist.

If maintained in groups of less than mentioned above, they tend to be over dominate of each other and may force some members into hiding. The bigger the group, the less intergroup picking on each other exists.
