Chrysiptera

Chrysiptera rollandi

(Whitley, 1961)

Rolland's Demoiselle, Blackcap Damselfish

Likely Reef Tank Suitable

Likely Fish-Only Tank Suitable

Range: Eastern Indian Ocean and Western Pacific: Andaman Sea to Loyalty Islands, north to Philippines, south to Great Barrier Reef and New Caledonia.

Size: 3 inches (7 cm)

Natural Environment: Inhabits lagoons, harbors and outer reef slopes at depths between 6 to about 100 feet (2 – 30 m) and feeds on on planktonic crustaceans (copepods, mysis, and shrimp larvae), fish eggs and algae.

General Husbandry: Quite attractive and ocassionally available in the trade, with those collected in the Loyalty Islands, Fiji and New Caledonia having a yellow forehead, then a wide black slanted band, with the remaining body white. Those from other areas tend to have a greyish black head and frontal body, with the remaining body yellowish white.

Best maintained in aquariums having wide-open substrate swimming areas, as they tend to stay within several inches of the substrate in the wild.

Sometimes picked on by slightly more aggressive fishes.

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, and should also be offered several times daily.
