Chrysiptera

Chrysiptera caeruleolineata

(Allen, 1973)

Blueline Demoiselle, Blueline Damselfish

Likely Reef Tank Suitable

Likely Fish-Only Tank Suitable

Range: Indo-West Pacific Ocean: Eastern Indian Ocean to New Guinea, Coral Sea, Solomon Islands, Fiji, Samoa, Guam, and Southern Japan, and Australia coastal reefs.

Size: 3 inches (8 cm)

Natural Environment: Inhabits deep rubble areas, rocky outcrops and sand channels in steep outer reef slopes at depths between 65 to about 200 feet (20 – 60 m) and mainly feeds on planktonic crustaceans (copepods, mysis, and shrimp larvae), and fish eggs.

General Husbandry: Rarely seen the trade, this quite attractive species is one of the better behaved members in this genus and usually makes a good addition to a peaceful community fish home aquarium. Has a yellowish body with a upper body bright blue horizontal streak edged in black from snout rearwards to the aft body.

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, a meaty diet, e.g., live fortified brine shrimp and/or finely chopped various frozen or fresh meaty foods such as mysis, squid, fish flesh, shrimp, clam and plant material, e.g., flake foods, especially those containing Spirulina should also be offered several times daily.

Taxonomy:

    Order: Perciformes

    Suborder: Labroidei

    Family: Pomacentridae

    Subfamily: Pomacentrinae

    Genus: Chrysiptera

FYI: Even though quite peaceful, may annoy smaller more peaceful fishes, especially if those are introduced after it was added to the aquarium.

May be maintained in small groups if desired; yet best accomplished in larger aquariums, e.g., 50+ gallons, as they tend to pick on each other in smaller aquariums.
