Chromis lineata

Fowler & Bean, 1928

Lined Chromis

Range: Indo-West Pacific Ocean: Christmas Island, Indonesia, Philippines, Palau, New Guinea, New Britain, Solomon Islands, and the northern Great Barrier Reef.

Size: 3 inches (7 cm)

Natural Environment: Inhabits coral rich upper areas of outer reef slopes often near caves at depths between 6 to about 100 feet (2 – 30 m) where it feeds mainly on planktonic crustaceans (copepods, mysis, and shrimp larvae), fish eggs, and algae.

General Husbandry: Rarely seen in the trade, having a very plain lined greenish body.

As with most Chromis species, quite hardy, peaceful, and better maintained in small groups of at least five to seven members. Should be given wide-open swimming areas, as they are open water swimmers almost always in the upper aquarium areas, and non-aggressive tankmates.

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., 50 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.
