P. annularis is a tropical, marine (salt water) fish that lives around coastal rocky coral reefs and other hard bottom coastal areas. In their natural habitat the adults are normally found from 5-15 meters in depth, but as far down as 30 meters. The juveniles are usually at the upper range of the adults and sometimes are in even shallower water. When kept as aquarium fish, optimal temperature is 26 degrees Celsius with a pH of 8 and lots of light.
The adults of the genus Pomacanthus are normally haremic; one male defends a territory with two to five females living with the male. They are usually found alone or in pairs in caves in the rocky/coral oceanic bottom (Steen, 1978; Tullock, 1996; Agbayani, 2002).
Range depth: 3 to 30 m.
Average depth: 5-15 m.
Habitat Regions: tropical ; saltwater or marine
Aquatic Biomes: benthic ; reef ; coastal
Pomacanthus annularis live in the Indo-Pacific region ranging from Sri Lanka to the Solomon Islands and from the Philippines to the northern tip of Australia. Normally this range is from 25 degrees north to 25 degrees south (Agbayani, 2002; Heemstra, 1986).
Biogeographic Regions: oriental (Native ); australian (Native ); indian ocean (Native ); pacific ocean (Native )
P. annularis are omnivorous, eating benthic invertebrates such as zooplankton, sponges, tunicates and coral polyps. Also these fish eat ascidians, algae, weeds, and nektonic fishes (Steen, 1978; Agbayani, 2002).
Animal Foods: cnidarians; other marine invertebrates
Plant Foods: leaves; algae
Primary Diet: carnivore (Piscivore , Eats other marine invertebrates); herbivore (Folivore , Algivore); omnivore ; planktivore
Adult P. annularis are a dark orange to brown color with white caudal fin, grow up to 12 inches in length, head to caudal fin and are monomorphic between sexes. Soft dorsal spine rays, numbering 20-21 are at times longer than normal so that they extend further than the rest of the dorsal spine rays. There are also 13 dorsal spines with the dorsal fins being continuous, three anal spines and 20 soft anal rays (Agbayani, 2002). Adult bluering angelfish have blue, horizontal curved lines that extend from the back of the head/pelvic fin area to the dorsal and caudal fins. Also there are two blue stripes that cross the face, one through the eye and the other below. Finally, the blue ring (where it gets its common name) is above and behind the operculum (Agbayani, 2002; Nelson, 1994; Thresher, 1984; Heemstra, 1986).
Members of the family Pomacanthidae were classified until recently in a family with butterfly fishes because they share many features "such as deep compressed bodies, ctenoid scales which extend out onto the median fins, a small mouth with brush-like teeth. But differ from butterfly fishes, however, in having a long spine at the corner of the preopercle (also smaller spines on the preopercle, opercle, and preorbital) (Allen, 1994). Other differences include the presence of a snout in angelfish and a pelvic axillary process (Helfman et al., 1997).
Range length: 20 to 45 cm.
Average length: 30.5 cm.
Other Physical Features: bilateral symmetry
Some large angelfish, such as the P. annularis have been recorded to live up to 25 years in an aquarium (www.sphyraena.com/library/angelfish.html).
Range lifespan
Status: captivity: 25 (high) years.
The bluering angelfish is kept as an aquarium fish and is exported regularly from Sri Lanka (Ceylon) to the US and Europe (Heemstra, 1986; Agbayani, 2002).
Positive Impacts: pet trade
None
The larvae hatch at sunset the day after the courtship ritual of the parents and swim with the plankton for a month before developing into juveniles. This type of fish is not able to reproduce well in captivity because the larvae are unable to survive. The fish are considered protogynous hermaphrodites, meaning at the beginning of life all are females. Then as development continues the larger fish become males (Tullock, 1996).
Also during development a drastic change occurs in the coloration patterns of juvenile P. annularis to the adult. The juveniles start out with alternating, vertical blue and white stripes on a black background. This coloration pattern is similar to all large angelfish and P. annularis juveniles often are misidentified as P. chrysurus. However, the caudal fin is transparent in bluering angelfish but is yellow in P. chrysurus. Then as they mature into adults, the vertical blue and white stripes disappear, the caudal fin whitens, and the background becomes a dark orange to brown. Horizontal, curved blue lines also appear and run from the back of the head/pelvic fin area to the caudal and dorsal fins (Agbayani, 2002; Heemstra, 1986).
Development - Life Cycle: metamorphosis
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
Perception Channels: tactile ; chemical
Mating System: polygynous
For members of the genus Pomacanthus, spawning normally begins with the onset of dusk and is thought to be triggered by the decrease in light. However it is not known whether there is a correlation between time of year or with the lunar cycle and the onset of spawning in angelfish. The adults have a courtship ritual that ends in the male and female slowly swimming toward the surface of the water and releasing eggs and sperm. The larvae then swim with the plankton for a month before continuing development. Spawning is thought to take place between only one male and one female at a time, but males possibly mate with more than one female with in the group (Thresher, 1984; Agbayani, 2002; Tullock, 2002).
Range gestation period: 15 to 24 hours.
Average gestation period: 20 hours.
Key Reproductive Features: year-round breeding ; sequential hermaphrodite (Protogynous ); sexual ; fertilization (External )
Parental Investment: no parental involvement
Der Ringkaiserfisch (Pomacanthus annularis) ist eine Art der Gattung Pomacanthus aus der Familie der Kaiserfische (Pomacanthidae).
Ringkaiserfische werden bis zu 30 Zentimeter lang. Ihre Körpergrundfarbe ist braungelb. Blaue Streifen erstrecken sich vom Kopf ausgehend über den Körper und enden in der leicht ausgezogenen Rückenflosse. Die Schwanzflosse ist weiß.
Junge Ringkaiserfische sind dunkelblau mit hellblauen und weißen senkrechten Streifen am Körper.
Er lebt im tropischen Indopazifik, von der Küste Ostafrikas bis nach Japan und zu den Fidschi-Inseln. Ringkaiserfische leben allein in Tiefen von 1 bis 30 Metern. Dabei bevorzugen sie Korallen- und Schwammreiche Regionen.
Ringkaiserfische ernähren sich von Schwämmen, Seescheiden und Algen.
Ringkaiserfische werden gelegentlich für Haltung in Meerwasseraquarien importiert. Verantwortliche Liebhaber sollten vom Kauf absehen, da man Tieren dieser Größe keinen angemessenen Lebensraum bieten kann. Zudem ist der Ringkaiserfisch neben dem Pfauen-Kaiserfisch (Pygoplytes diacanthus) der empfindlichste Großkaiserfisch.

The bluering angelfish (Pomacanthus annularis), also known as the Annularis Angelfish and the Blue King Angelfish, is a species of marine ray-finned fish, a marine angelfish belonging to the family Pomacanthidae.[3] It is member of the genus Pomacanthus, composed of large marine angelfish. [4]
The bluering angelfish can be found in the Indo-West Pacific oceans from East Africa, throughout Indonesia and New Guinea to New Caledonia, north to southern Japan. [5]
Bluering angelfishes inhabit coastal rocky coral reefs and may be also encountered in caves or on wrecks, at depths of 3–30 m (9.8–98.4 ft).[5][6][1]
Bluering angelfish have adults which are mainly yellow with the body marked with obvious arcing blue lines and a blue circle shaped mark above the operculum. They frequently have an elongated tip to the dorsal fin and they have a white caudal fin with a yellow margin.[7] They also have a pair of blue stripes across the face, one runs through the eye and the second is situated immediately beneath the eye.[8] The juveniles have a bluish-black overall colour with thin white to blue coloured curved lines on their body.[7] The dorsal fin has 13 spines and 20-21 soft rays while the anal fin contains 3 spines and 20 soft rays. This species attains a maximum total length of 45 cm (18 in).[5]
Bluering angelfishes are frequently encountered in pairs. Similarly to other species of the genus Pomacanthus these angelfishes live in harem, as the male defends a territory and controls a few females. After a courtship ritual males and females release eggs and sperm. At the beginning of life all juveniles are females (protogynous hermaphrodites), becoming males during the development, with a complete color variation from the juvenile to adult stage.[6] Juveniles prefer very shallow waters with rock or dead coral substrates and short filamentous algae. Adults mainly feed on zooplankton, sponges, filamentous algae and tunicates. [5][9]
The bluering angelfish was first formally described in 1795 as Chaetodon tricolor by the German physician and naturalist Marcus Elieser Bloch (1723–1799) with the type locality given as the Indian Ocean.[10] The species is placed by some authorities in the subgenus Acanthochaetodon,. The specific name of this species, annularis, means “ringed” which refers to the ring on the body above the gill cover.[11]
Bluering angelfish are infrequently found in the aquarium trade. [1]

Pomacanthus annularis, conosciuto comunemente come pesce angelo ad anelli blu, è un pesce angelo della famiglia Pomacanthidae che si trova nella regione Indo-Pacifica, dall’Africa dell'est fino al sud del Giappone, passando per l’Indonesia, la Nuova Guinea e la Nuova Caledonia.
È un membro altamente ricercato e apprezzato del genere Pomacanthus, che è composto da grandi pesci angelo. Il pesce angelo blu-cerchiato può raggiungere i 12 pollici allo stato libero, e può spesso arrivare alle stesse lunghezze anche in cattività.
Presenta considerevoli somiglianze con il pesce angelo imperatore, come il cambiamento di colore durante lo sviluppo dall'età giovanile a quella adulta. Gli esemplari giovani del pesce angelo ad anelli blu sono inizialmente blu scuro, quasi neri, con ampie striature verticali di colore bianco e turchese. In età adulta presentano un colore viola con linee semicircolari al centro del corpo.
In acquario i pesci angelo ad anelli blu si nutrono di alghe, ma consumano anche pesce e corallo. È risaputo che mangino gamberetti e rosicchino coralli duri a polipo grande e piccolo. In generale, gran parte degli acquaristi esperti sconsiglia di tenere questa specie in un acquario corallino a causa di quest'abitudine.

Pomacanthus annularis, thường được gọi là cá thần tiên vòng xanh, là một loài cá biển thuộc chi Pomacanthus trong họ Cá bướm gai. Loài này được mô tả lần đầu tiên vào năm 1787.
P. annularis được phân bố khá rộng rãi (trong đó có Việt Nam), trải dài từ bờ biển Đông Phi, băng qua Ấn Độ Dương, tới quần đảo Solomon (phía tây Thái Bình Dương); phía bắc giới hạn tới miền nam Nhật Bản và phía nam tới đảo New Caledonia. P. annularis ưa sống ở vùng nước đục, thường sống xung quanh các rạn san hô ven biển, đôi khi bắt gặp chúng trong các hang động, trong xác tàu, hoặc bên dưới cầu cảng, ở độ sâu khoảng 1 – 60 m[1][2].
P. annularis trưởng thành dài khoảng 45 cm. P. annularis có những sọc cong lượn màu xanh da trời trên nền màu vàng nâu của cơ thể; vây đuôi có màu trắng. Tên gọi của nó bắt nguồn từ đốm tròn màu cam ở trên nắp mang. Cá chưa trưởng thành có màu xanh đen với các dải sọc màu trắng, ngoại trừ vây đuôi có màu trắng đục[3].
Cá mới lớn của các loài trong chi Pomacanthus thường rất giống nhau, vì thế mà cá con P. annularis thường bị nhầm lẫn với Pomacanthus maculosus, Pomacanthus rhomboides, Pomacanthus chrysurus[3]. Cá con thường sống ở những vùng biển nông gần bờ, xung quanh các mỏm đá và san hô chết[1][2].
Thức ăn chủ yếu của P. annularis là những loài sinh vật phù du, động vật giáp xác, động vật không xương sống và rong tảo[1][2]. P. annularis thường sống đơn lẻ[1][2].
P. annularis thường được đánh bắt để phục vụ cho ngành thương mại cá cảnh[1][2].

Охранный статус
Ангел-анулярис (лат. Pomacanthus annularis) — вид тропических морских рыб из рода Pomacanthus семейства Pomacanthidae. Обитает в Индо-Тихоокеанской области от Восточной Африки, Индонезии и Новой Гвинеи до Новой Каледонии и юга Японии.
Ангел-анулярис является очень востребованным и ценным видом рода Помаканты. Как в дикой природе, так и в неволе, ангел-анулярис может достигать длины до 30 см.
Ангел-анулярис имеет значительное сходство с императорским ангелом в том, что оба вида претерпевают изменения окраски от юности к зрелости. Молодые особи вида ангел-анулярис тёмно-синие, почти черные, с широкими бирюзовыми и белыми вертикальными полосами. Взрослые особи имеют фиолетовую окраску с полукруглыми отметинами в середине тела.
В неволе рыбы вида ангел-анулярис едят не только водоросли, но также рыбу и кораллы. Кроме того, известно, что они питаются креветками, большими и малыми рифообразующими кораллами. Из-за этого опытные аквариумисты не рекомендуют содержать этот вид рыб в рифовом аквариуме.
