C. potteri is part of the already threatened coral reef ecosystems. Therefore, it is important to not take too many individuals for the pet trade.
US Migratory Bird Act: no special status
US Federal List: no special status
CITES: no special status
IUCN Red List of Threatened Species: least concern
Individuals are orange with narrow, black, vertical stripes and a blue lining of the dorsal, anal and caudal fins. Unlike most other pygmy angelfish, Potter's angelfish has a preopercular spine (Gosline, 1960).
Average length: 10 cm.
Other Physical Features: bilateral symmetry
C. potteri is a pygmy angelfish, and does not live as long as its larger relatives. The average lifespan for the Potter's angelfish is six years in the wild (Tinker, 1944).
Typical lifespan
Status: wild: 5 to 7 years.
C. potteri inhabits coral reef ecosystems at least 15 feet in depth (Gosline, 1960).
Range depth: 4.5 (low) m.
Habitat Regions: tropical ; saltwater or marine
Aquatic Biomes: reef
Centropyge potteri is endemic to the Hawaiian islands and Johnston's atoll between 30 and 17 degrees north latitude (Carlson, 2000).
Biogeographic Regions: neotropical (Native ); oceanic islands (Native )
Other Geographic Terms: island endemic
Individuals use their many comblike teeth to pull food items off of hard reef surfaces. Their diet consists of benthic algae, cnidarians, and tunicates (Carlson, 2000).
Animal Foods: cnidarians; other marine invertebrates
Plant Foods: algae
Primary Diet: carnivore (Eats other marine invertebrates); herbivore (Algivore); omnivore
C. potteri is an integral part of the biodiversity of the reef ecosystem.
C. potteri adds to beauty of coral reefs, which are one of the main Hawaiian tourist attractions. This species is also kept as a pet (Carlson, 2000).
Positive Impacts: pet trade ; ecotourism
Potter's angelfish in no way harms humans, the environment, or the economy.
C. potteri is a protogynous species, which means that most individuals begin their lives as small females, and then change into males when they are large enough to control a harem of two to seven females and breeding territory for reproduction. This sex inversion takes place over two to three weeks (Lutnesky, 1996).
Laboratory studies have detected a quiet chirping sound that is emitted during courtship; however its purpose is unclear (Lutnesky and Kosaki, 1995).
Communication Channels: acoustic
Perception Channels: tactile ; chemical
The main anti-predator strategy that the small angelfish uses is to hide within finger coral crevices and remain inactive at night. Its narrow body also allows for fast swimming and darting motions to escape predators (Carlson, 2000).
Known Predators:
A single male maintains a harem in his territory and will fertilize the eggs of several females within a single spawning season.
Mating System: polygynous
Males must be large enough to control a harem and secure breeding rights, as this species is polygynous. Males visit haremic females near their reef and display courtship by swimming around the females in circles and then each individual simultaneously releases its gametes into the water, where fertilization occurs (Lutnesky and Kosaki, 1995).
Breeding season: Mid-December through May, spawns week before full moon at dusk
Key Reproductive Features: iteroparous ; seasonal breeding ; sequential hermaphrodite (Protogynous ); sexual ; fertilization (External )
Adult Potter's angelfish do not care for the eggs or fry.
Parental Investment: no parental involvement
Potters Zwergkaiserfisch (Centropyge potteri) lebt im Pazifik bei Hawaii, wurde aber auch schon bei den Midwayinseln und beim Johnston-Atoll gesehen. Er bevorzugt Außenriffe, Fels- und Geröllgrund in Tiefen von unter zehn Metern bis zu 138 Metern; Jungfische halten sich auch in Tiefen ab fünf Metern auf. Die Vertreter dieser häufig vorkommenden Fischart verlassen nie die nähere Umgebung ihres jeweiligen Versteckplatzes. Das Artepitheton bekamen sie zu Ehren des ersten Direktors des Waikiki Aquariums in Hawaii, Frederick Potter.
Potters Zwergkaiserfisch ernährt sich von Algen und Detritus. Seine Hauptfortpflanzungszeit ist von Mitte Dezember bis Mai. Er laicht in der Dämmerung, jeweils in der Woche vor Vollmond.
Diese Zwergkaiserfisch-Art wird zehn Zentimeter lang. Sie ist von oranger Grundfarbe und von einem netzartigen Geflecht grüner Querstreifen überzogen. Rücken-, Schwanz- und Afterflosse haben leuchtend blaue Streifen. Brust- und Bauchflossen sind hellorange bis gelb. Die leuchtend orange Färbung der Tiere ist im natürlichen Lebensraum meist nicht sichtbar, da der rote Anteil des Sonnenlichtes in diesen Tiefen vom Wasser absorbiert wird, und erscheint dort braun oder grüngrau.

Centropyge potteri, commonly known as the russet angelfish, Potter's angelfish or Potter's pygmy angelfish, is a species of marine ray-finned fish, a marine angelfish belonging to the family Pomacanthidae. It is found in the central Pacific Ocean.
Centropyge potteri' has a bright orange body marked with thin vertical stripes which are blue to black in colour.[3] The dorsal, caudal and anal fins have a vivid blue margin while the pectoral and pelvic fins are orange to bright yellow in colour.[2] The males have a wider area of blue in the middle of the body which extends down on to the belly. There is a deep water vivid blue colour morph in which the stripe are black or purple that has black to burgundy stripes, which occurs at depths below 60 metres (200 ft).[3] This species attains a maximum total length of 10 centimetres (3.9 in).[2]
Centropyge potteri is found in the central Pacific Ocean where it is found around the Hawaiian Islands and Johnston Atoll.[1]
Centropyge potteri is found at depths between 10 and 120 metres (33 and 394 ft).[1] This species lives in areas of rock, coral or rubble on seaward reefs. Juveniles are occasionally recorded in waters as shallow as 5 metres (16 ft). It is a benthopelagic species which feeds on algae and detritus.[2] They mnay live in small social groups, harems with a single male and up to 8 females.[4] They are protogynous hermaphrodites and if no male is present the dominant female will change sex.[5] Spawning takes place between December and May and usually occurs around nightfall. A spawning pair will select a high outcropping of rock in their territory to spawn over. The male initiates courtship by approaching the female and swimming alongside the female in a vertical position and using a smooth sinuous motion. He then moves to be above the female, halts, raises his dorsal and anal fin, starts to flutter the pectoral fins and makes a slight sideward turn before starting to drift slowly. If he does not elicit a response he will start again with the sinuous swimming notion, repeating until the female responds. When they are ready to mate the red colouration becomes more intense and the par make audible grunts and clicks. The male will then draw the female to the selected outcropping and will continue the display around 90cm above it. When the female adopts the position that indicates she is ready to mate, the male briefly nuzzles her vent until she releases the eggs. The male then immediately releases his milt and then both fish dive for cover, the female chasing the male and nipping at his caudal fin. They then go to their night time shelter.[3]
Centropyge potteri was first formally described in 1912 by the American ichthyologists David Starr Jordan (1851-1931) and Charles William Metz (1889-1975) with the type locality given as Honolulu on Oahu.[6] The specific name honours Frederick A. Potter the first director of the Waikiki Aquarium who held the post from 1904 to 1940. Some authorities place this species in the subgenus Centropyge.[7]
Centropyge potteri appears in the aquarium trade.[1]

Aaltoherttuakala (Centropyge potteri) on keisarikalojen heimoon kuuluva kalalaji.
Aaltoherttuakala kasvaa noin 10 cm pitkäksi. Sen pohjaväri on oranssinsävyinen ruosteenruskea, tummenee kohti alaperää. Tumma alue erottuu selkeämmin koirailla kuin naarailla. Kalan kuviointi on lemmikinsinisiä juovia.[2]
Aaltoherttuakala on kotoperäinen laji Havaijilla ja Johnstonin atollilla.[2] Ne viihtyvät riuttojen merenpuolisilla rinteillä kallio-, kivikkoa- tai korallipohjan päällä. Nuoret yksilöt uivat joskus 5 m:n syvyydessä, aikuiset kalat syvemmällä.[3]
Aaltoherttuakalat ovat syntyessään sukupuolettomia, muut kehittyvät aikuistuessaan naaraiksi mutta parven voimakkaimmasta kalasta tulee koiras.[2] Ne kutevat iltahämärän aikaan viikkoa ennen täysikuuta.[3]
Aaltoherttuakalat syövät levää ja muuta merenpohjan kariketta.[1]
Aaltoherttuakaloja pidetään meriakvaarioissa. Ne pärjäävät parhaiten riutta-akvaariossa, mutta saattavat näykkiä koralleja tai merivuokkoja ja muita selkärangattomia. Kalan on hiukan vaikea tottua syömään valmisruokia kuten hiutaleita, ja siksi ne sopeutuvat parhaiten kypsiin riutta-akvaarioihin, joissa on paljon elävää kiveä jonka pinnalta kala voi aluksi syödä levää ja lietettä.[2]

Centropyge potteri is een straalvinnige vissensoort uit de familie van engel- of keizersvissen (Pomacanthidae).[2] De wetenschappelijke naam van de soort was oorspronkelijk Holacanthus potteri en werd in 1912 gepubliceerd door Jordan & Metz.[3]
De soort staat op de Rode Lijst van de IUCN als niet bedreigd, beoordelingsjaar 2009. De omvang van de populatie is volgens de IUCN stabiel.[1] Ze komt voor in de Stille Oceaan bij Hawaii en leeft bij voorkeur in koraalriffen. De vissen worden ca. 10 centimeter groot.
Het epitheton potteri is een eerbetoon aan Frederic Potter, de directeur van het Waikiki-aquarium in Honolulu, waar D. S. Jordan het dier opmerkte en identificeerde als een nieuwe soort. Potter schonk het type aan het United States National Museum.
