Metynnis maculatus, the spotted metynnis, is a species of serrasalmid fish found in Argentina and Brazil, and possibly in Bolivia, Paraguay, and Peru. It is one of the species of fish known in the aquarium trade as the "silver dollar".
The southern platyfish, common platy, or moonfish is a species of freshwater fish in family Poeciliidae of order Cyprinodontiformes. A live-bearer, it is closely related to the green swordtail and can interbreed with it. It is native to an area of North and Central America stretching from Veracruz, Mexico, to northern Belize.
The king mackerelsurmayi or kingfish, is a migratory species of mackerel of the western Atlantic Ocean and Gulf of Mexico. It is an important species to both the commercial and recreational fishing industries.
Metynnis hypsauchen is a species of serrasalmid found in Amazon and Paraguay river basins, as well as rivers of the Guiana Shield. It is one of the fish known as the "silver dollar" in the aquarium trade. It has frequently been confused with the very similar M. argenteus. It reaches a length of 15 cm (5.9 in).
Silver dollar is a common name given to a number of species of fishes, mostly in the genus Metynnis, tropical fish belonging to the family Serrasalmidae which are closely related to piranha and pacu. Most commonly, the name refers to Metynnis argenteus. Native to South America, these somewhat round-shaped silver fish are popular with fish-keeping hobbyists.
Wobbegong is the common name given to the 12 species of carpet sharks in the family Orectolobidae. They are found in shallow temperate and tropical waters of the western Pacific Ocean and eastern Indian Ocean, chiefly around Australia and Indonesia, although one species occurs as far north as Japan. The word wobbegong is believed to come from an Australian Aboriginal language, meaning "shaggy beard", referring to the growths around the mouth of the shark of the western Pacific.
The Atlantic Spanish mackerel is a migratory species of mackerel that swims to the northern Gulf of Mexico in spring, returns to southern Florida in the eastern Gulf, and to Mexico in the western Gulf in the fall.
The Galaxiidae are a family of mostly small freshwater fish in the Southern Hemisphere. The majority live in Southern Australia or New Zealand, but some are found in South Africa, southern South America, Lord Howe Island, New Caledonia, and the Falkland Islands. One galaxiid species, the common galaxias, is probably the most widely naturally distributed freshwater fish in the Southern Hemisphere. They are coolwater species, found in temperate latitudes, with only one species known from subtropical habitats. Many specialise in living in cold, high-altitude upland rivers, streams, and lakes.
The hogchoker is a small species of flatfish found along the Atlantic and Gulf coasts of North and South America, ranging from Massachusetts to Venezuela. They prefer brackish water, and are abundant in many bays and estuaries north of the Carolinas. It is a member of the American sole family Achiridae. They are usually brown to dark brown in color, and lighter on their "blind side". The overall body color is often broken by a series of spots and thin stripes, which can be lighter or darker than the main body color. The fins and tail have fringed edges helping hide the fish from its prey. They mainly feed on small aquatic insects and invertebrates. They get their common name because East Coast fishermen would feed these so-called "trash" fish to their hogs, after which the fish would bow its body into a suction cup and stick to the soft palate of the hog, rather like peanut butter in a dog’s mouth.
The common galaxias or inanga is a very widespread Southern Hemisphere fish in the family Galaxiidae. It is a slim, narrow fish with a forked tail and a mottled, spotty pattern, typically about 10 cm (4 in) long when fully grown. It lives in fresh water, but spawns at river mouths and spends the first six months of its life at sea, returning en masse in spring. Its vernacular names include cowfish, jollytail, common jollytail, eel gudgeon, inaka, native trout, pulangi, puye, slippery tarki, spotted minnow, Falklands minnow and whitebait.
The Serrasalmidae (serrasalmids) are a family of characiform fishes, recently elevated to family status. It includes more than 90 species. The name means "serrated salmon family", which refers to the serrated keel running along the belly of these fish. Fish classified as Serrasalmidae are also known by these common names: pacu, piranha, and silver dollar. These common names generally designate differing dental characteristics and feeding habits.
The spotted wobbegong is a carpet shark in the family Orectolobidae, endemic to Australia. It is a large, robust species, typically reaching 150–180 centimetres (59–71 in) in length. Coloured green, yellow, or brown, it has distinctive O-shaped spots throughout its body. It is nocturnal, resting at day and feeding on fish and invertebrates at night. An ovoviviparous species, the spotted wobbegong gives birth in the spring, during which time males can act aggressively towards other males and females. It has been known to bite humans, sometimes unprovoked, which can produce severe wounds. The species is fished commercially in Australia, but it is not severely threatened. It is listed as a least-concern species on the IUCN Red List.
Schroederichthys is a genus of catsharks in the family Scyliorhinidae.
The narrowtail catshark is a catshark of the family Scyliorhinidae, found off the coasts of Honduras and Nicaragua, between latitudes 18° N and 10° N, at depths between 190 and 410 m. It can grow up to a length of 35 cm (14 in). The reproduction of this catshark is oviparous.
The orange chromide is a species of cichlid fish that is endemic to freshwater and brackish streams, lagoons and estuaries in southern India and Sri Lanka. It is also known as pallathi in Malayalam. The species is popular with fishkeeping hobbyists, and is kept frequently in aquariums. The species is part of the family Cichlidae and is included in subfamily Etroplinae. The orange chromide reaches a length of up to 8 cm (3.1 in).
The green chromide is a species of cichlid fish that is native to fresh and brackish water habitats in some parts in India such as Kerala, Goa, Chilika Lake in Odisha and Sri Lanka. The species was first described by Marcus Elieser Bloch in 1790. This species and other members of the genus Etroplus are relatively closely related to the Paretroplus cichlids from Madagascar.
Orectolobus is a genus of carpet sharks in the family Orectolobidae. They are commonly known as wobbegongs, although this name also applies to the other members of the family. They are found in shallow temperate and tropical waters of the western Pacific Ocean and eastern Indian Ocean, chiefly around Australia and Indonesia, although one species occurs as far north as Japan.
The Serra Spanish mackerel is a species of fish in the family Scombridae. Specimens have been recorded at up to 125 cm in length, and weighing up to 6.71 kg. It is found in the western Atlantic, along the Caribbean and Atlantic coasts of Central and South America from Belize to Rio Grande do Sul, Brazil. Literature records for S. maculatus from the area apply to S. brasiliensis, which has erroneously been considered a synonym of S. maculatus by many authors. It feeds on small fish, squid/cuttlefish, shrimp/prawn, and isopods.
Anabarilius maculatus is a species of cyprinid fish in the family Xenocyprididae. It is endemic to the Nan Pan Jiang basin in Yunnan, southern China. It is threatened by invasive non-native species, domestic and urban waste water, agricultural pollution and dams. The species have not been studied well, therefore its ranked as Data Deficient. It grows to 13.9 cm (5.5 in) standard length.
Opsarius is a genus of fish. Its representatives can be found in a variety of countries in South East Asia. These countries include Cambodia, Laos, Thailand, Myanmar, India, and China. Certain species of Opsarius are considered endemic to their respective habitats; such as Opsarius cocsa and Opsariusmaculatus which are endemic to India.
Metynnis is a genus of serrasalmid fish from tropical and subtropical South America. They are herbivorous or omnivorous, and inhabit a wide range of freshwater habitats, ranging from rivers and streams, to floodplains, flooded forests, lakes, pools and reservoirs. They generally reach 8–15 cm (3–6 in) in standard length, although a few species may reach up to 18 cm (7 in). The genus contains many of the species known as silver dollars in the aquarium trade.
