Pomacanthidae
Marine angelfish are perciform fish of the family Pomacanthidae. They are found on shallow reefs in the tropical Atlantic, Indian, and mostly western Pacific Oceans. The family contains seven genera and about 86 species. They should not be confused with the freshwater angelfish, tropical cichlids of the Amazon Basin. Description With their bright colours and deep, laterally compressed bodies, marine angelfishes are some of the more conspicuous residents of the reef. They most closely resemble the butterflyfishes, a related family of similarly showy reef fish. Marine angelfish are distinguished from butterflyfish by the presence of strong preopercle spines (part of the gill covers) in the former. This feature also explains the family name Pomacanthidae; from the Greek πομα, ''poma'' meaning "cover" and ακάνθα, ''akantha'' meaning "thorn". Many species of marine angelfishes have streamer-like extensions of the soft dorsal and anal fins. The fish have small mouths ...

Queen Angelfish
The queen angelfish (''Holacanthus ciliaris''), also known as the blue angelfish, golden angelfish, or yellow angelfish, is a species of Pomacanthidae, marine angelfish found in the western Atlantic Ocean. It is a benthic zone, benthic (ocean floor) warm-water species that lives in coral reefs. It is recognized by its blue and yellow coloration and a distinctive spot or "crown" on its forehead. This crown distinguishes it from the closely related and similar-looking Bermuda blue angelfish (''Holacanthus bermudensis''), with which it overlaps in range and can interbreed. Adult queen angelfish are selective feeders and primarily eat sponges. Their social structure consists of harem (zoology), harems which include one male and up to four females. They live within a territory (animal), territory where the females forage separately and are tended to by the male. Spawn (biology), Breeding in the species occurs near a full moon. The transparent Ichthyoplankton, eggs float in the water ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
French Angelfish
''Pomacanthus paru'', also known by its common name the French angelfish, is a slow growing coral reef fish from the Caribbean. The species is of the family Pomacanthidae, which contains other species of marine angelfish. Its closest relative is the grey angelfish (''P. arcuatus''). Taxonomy The French angelfish was first formally described as ''Chaetodon paru'' by the German physician and naturalist Marcus Elieser Bloch (1723–1799) with the type locality given as Brazil and Jamaica. The species is placed by some authorities in the subgenus ''Pomacanthus'',. The specific name of this species, ''paru'' is the Portuguese name for this species. Description The French angelfish has a deep but vertically compressed body, making it appear flattened from the front. The head is deep, with a short snout that ends in a small mouth containing numerous bristle-like teeth. There is an obvious spine at the corner of the preoperculum while there are no spines on the operculum or under ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Centropyge
''Centropyge'' is a genus of ray-finned fish, marine angelfish belonging to the family (biology), family Pomacanthidae found in the Atlantic Ocean, Atlantic, Indian Ocean, Indian and Pacific Ocean. These species do not exceed 15 centimeter, cm in fish measurement, length and live in haremic structures with one dominant male and multiple females. Taxonomy ''Centropyge'' is a Paraphyly, paraphyletic genus. This is because ''Genicanthus'' and the Polyphyly, polyphyletic genus ''Apolemichthys'' are nested within ''Centropyge''. ''Centropyge'' includes 3 Subgenus, subgenera and several Species complex, species complexes. The subgenus ''Xiphypops'' only comprises all species within the ''C. acanthops'' complex, which include Orangeback angelfish, ''C. acanthops'', ''Cherubfish, C. argi'', ''Flameback angelfish, C. aurantonota'', ''Resplendent pygmy angelfish, C. resplendens''. Subgenus ''Paracentropyge multifasciata, Paracentropyge'' comprises ''Peppermint angelfish, C. boylei'', '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genicanthus
''Genicanthus'' is a genus of marine angelfishes in the family Pomacanthidae. Known commonly as swallowtail or lyretail angelfish, these fishes are so-named for the distinctive shape of their tailfins. This genus of angels, in comparison to the other species found in hobby aquaria, are a good choice for beginners as they do not get nearly as large as some of the others. Another unique attribute is that swallowtail angels will tolerate each other and can be kept in pairs or as a single male with a harem, though it is typically best to add them to a tank at the same time. If added on by one, the angel which is added first may become aggressively territorial towards any new additions. Unlike others in the family Pomocanthidae, the angelfish species in the genus ''Genicanthus'' are generally considered to be reef safe. Also unlike most other members of the Pomacanthidae, those in ''Genicanthus'' are sexually dimorphic, meaning males and females are easily distinguishable. Fish in t ...

Regal Angelfish
The royal angelfish (''Pygoplites diacanthus''), or regal angelfish, is a species of marine ray-finned fish, a marine angelfish belonging to the family (biology), family Pomacanthidae, and the monotypic genus ''Pygoplites''. It is found in tropical Indo-Pacific oceans. It can grow as long as . Description The body of the royal angelfish is moderately elongate and is very compressed. The preorbital bone is convex and has no strong spines. There is 1 prominent spine at an angle at the preopercal. The ventral edge of the interopercle is smooth. The eyes are moderately small along with the mouth that is terminal. The mouth is also protractile. They have a maximum length of . They have a total of 14 dorsal spines, and 17–19 soft dorsal rays. They have 3 anal spines and 17–19 anal soft rays. They also have 16–17 pectoral fin rays. Their caudal fin is rounded. The precise coloration of this fish can vary as regional differences can occur, most notably in populations from the Ind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Butterflyfish
The butterflyfish are a group of conspicuous tropical ocean, marine fish of the family Chaetodontidae; the bannerfish and coralfish are also included in this group. The approximately 129 species in 12 genera are found mostly on the reefs of the Atlantic Ocean, Atlantic, Indian Ocean, Indian, and Pacific Oceans. A number of species pairs occur in the Indian and Pacific Oceans, members of the huge genus ''Chaetodon''. Butterflyfish look like smaller versions of angelfish (Pomacanthidae), but unlike these, lack preopercle spines at the gill covers. Some members of the genus ''Heniochus'' resemble the Moorish idol (''Zanclus cornutus'') of the monotypic Zanclidae. Among the paraphyletic Perciformes, the former are probably not too distantly related to butterflyfish, whereas the Zanclidae seem far less close. Description and ecology Butterflyfish mostly range from in length. The largest species, the lined butterflyfish and the saddle butterflyfish, ''C. ephippium'', grow to . The ...

Anal Fin
Fins are moving appendages protruding from the body of fish that interact with water to generate thrust and help the fish swim. Apart from the tail or caudal fin, fish fins have no direct connection with the back bone and are supported only by muscles. Fish fins are distinctive anatomical features with varying structures among different clades: in ray-finned fish (Actinopterygii), fins are mainly composed of bony spines or rays covered by a thin stretch of scaleless skin; in lobe-finned fish ( Sarcopterygii) such as coelacanths and lungfish, fins are short rays based around a muscular central bud supported by jointed bones; in cartilaginous fish ( Chondrichthyes) and jawless fish ( Agnatha), fins are fleshy " flippers" supported by a cartilaginous skeleton. Fins at different locations of the fish body serve different purposes, and are divided into two groups: the midsagittal ''unpaired fins'' and the more laterally located ''paired fins''. Unpaired fins are pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gray Angelfish
The gray angelfish (''Pomacanthus arcuatus''), also written as grey angelfish and known in Jamaica as the pot cover, is a species of marine ray-finned fish belonging to the marine angelfish family, Pomacanthidae. It is found in the Western Atlantic Ocean. Description The gray angelfish has a disk-shaped, compressed body with a large head and small snout. The snout has a mouth at its tip, which is filled with small, bristle-like teeth. The preoperculum has a sizable spine at its corner and a smooth vertical edge. The juveniles have a black body marked with five vertical yellow stripes, three on the head and two on the body. The caudal fin has a black blotch which can be elongated or rectangular. Adults are pale grayish in color and covered in black spots. The head is plain pale gray with a white mouth. The dorsal and anal fins frequently show elongated streamers.

Pectoral Fin
Fins are moving appendages protruding from the body of fish that interact with water to generate thrust and help the fish aquatic locomotion, swim. Apart from the tail or caudal fin, fish fins have no direct connection with the vertebral column, back bone and are supported only by muscles. Fish fins are distinctive anatomical features with varying structures among different clades: in ray-finned fish (Actinopterygii), fins are mainly composed of bone, bony spine (zoology), spines or ray (fish fin anatomy), rays covered by a thin stretch of fish scale, scaleless skin; in lobe-finned fish (Sarcopterygii) such as coelacanths and lungfish, fins are short rays based around a muscular central limb bud, bud supported by appendicular skeleton, jointed bones; in cartilaginous fish (Chondrichthyes) and jawless fish (Agnatha), fins are fleshy "flipper (anatomy), flippers" supported by a cartilaginous skeleton. Fins at different locations of the fish body serve different purposes, and are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bluering Angelfish
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. It is member of the genus ''Pomacanthus'', composed of large marine angelfish. Distribution 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. Habitat Bluering angelfishes inhabit coastal rocky coral reefs and may be also encountered in caves or on wrecks, at depths of . Description 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. They also have a pair of blue stripes across the face, one runs through the eye and the second is situ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perciform
Perciformes (), also called the Acanthopteri, is an order or superorder of ray-finned fish in the clade Percomorpha. ''Perciformes'' means "perch-like". Among the well-known members of this group are perches and darters (Percidae), and also sea basses and groupers (Serranidae). This order contains many familiar freshwater temperate and tropical marine fish groups, but also extremophiles that have successfully colonized both the North and South Poles, as well as the deepest depths of the ocean. Taxonomy Formerly, this group was thought to be even more diverse than it is thought to be now, containing about 41% of all bony fish (about 10,000 species) and about 160 families, which is the most of any order within the vertebrates. However, many of these other families have since been reclassified within their own orders within the clade Percomorpha, significantly reducing the size of the group. In contrast to this splitting, other groups formerly considered distinct, such as the Sco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freshwater Angelfish
''Pterophyllum'' is a small genus of freshwater fish from the family Cichlidae known to most aquarists as angelfish. All ''Pterophyllum'' species originate in the Amazon Basin, Orinoco Basin and various rivers in the Guiana Shield in tropical South America. The three species of ''Pterophyllum'' are unusually shaped for cichlids, being greatly laterally compressed, with round bodies and elongated triangular dorsal and anal fins. This body shape allows them to hide among roots and plants, often on a vertical surface. Naturally occurring angelfish are frequently striped transversely, colouration which provides additional camouflage. Angelfish are ambush predators and prey on small fish and macroinvertebrates. All ''Pterophyllum'' species form monogamous pairs. Eggs are generally laid on a submerged log or a flattened leaf but can also be laid on filter piping when kept in an aqaurium setting. As is the case for other cichlids, brood care is highly developed. ''Pterophyllum'' sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
