Characteristics

Description

Orange-yellow body with thin irregular blue-gray vertical bands. Bluish black band centrally widening from front to rear. Black and blue horizontal bands on the caudal fin. Pectoral and pelvic fins usually bright yellow or orange.

If collected in a pair or as a harem the male is usually larger, have a greater percentage of bluish black colouring and brighter colouring overall.

Color morphs: blue with black vertical bars [1]

Known hybrids: C. loricula x C. potteri [2], C. fisheri x C. potteri (not confirmed)[3]

Similar Species

Maximum Size

About 10 cm [4].

Associated Organisms

No known.

Behaviour

A timid fish that constantly grazes on microalgae and detritus. Once established in a aquarium it is one of the more aggressive of the Centropyge members.

Rarely found far from cover in there natural environment.



Captive Care

Tank Size

300L

Water Flow

No specific requirements.

Lighting

No specific requirements.

Feeding

Natural diet consists of mainly filamentous algae and detritus material [5]

In captivity they are difficult to initially get eating. Open structure rockwork will provide microalgae growth and shelter. Once eating they will accept dry, frozen and live foods, plus grazing on algae.

Growth Rate

How quickly it will grow under various conditions.

Diseases

Survival during transport and acclimation is poor, often dying within 48 hrs - 10 days. Captive success maybe considered at longer then three months.

Dwarf angels are very susceptible to most common diseases.

Copper based medications should be avoided.

Other

Provide open structure rockwork preferably combined with live coral cover.

Compatability

Fish

Dwarf angels are territorial and agressive towards their own species and other Centropyge. Therefore, only one per tank should be kept. If adding more then one, select small and if known preferably female fish, introducing them at the same time.

Coral

Dwarf Angels are known coral nibblers. While nipping generally does not damage the coral tissue, it will cause the polyp to retract.

Invertebrate

Genrally considered safe.


Reproduction

C. potteri is a protogynous hermaphrodites, developing female reproductive organs as a juvenile. It may then change to male, consequently being the dominant female in the harem.

No known captive breeding to date.

In it's natural environment Lobel(1978)[6] noted that C. potteri is likely to form pairs over extensive reef and rubble habitats and harems on patch reefs. The peak reproduction period for C. potteri occurs from mid-December to June[7]. Courtship begins during the twilight hours in the week preceding a full moon[6][4] . A male entices a female to mid water, approximalty 1 meter above a predominant hight point where eggs and sperm are released into the water.[6] (palegic spawning). Clicking and gruting sounds can be heard during this spawning ritual.[6]

Local Ecology

Distribution

Hawaiian Islands [4] and Johnston Atoll.

Habitat

Rock, coral and rubble areas below about 10 metres [4], with juveniles often seen in shallower water.



Additional Information

Named after Frederick A. Potter, the first director of the Waikiki Aquarium.
