The Buenos Aires tetra (Psalidodon anisitsi) [3] is a tropical fish from South America. It was first observed in the wild in 1907, by Carl H. Eigenmann.
An aquarium subject for over 60 years, the Buenos Aires tetra is a well loved aquarium fish, often admired for its flashy red color.
The Buenos Aires tetra originates from South America, where they are widespread throughout the Río de la Plata Basin in Argentina, Paraguay, Uruguay, and southeastern Brazil. [4] Despite the common name, they are not endemic to its namesake, Buenos Aires Province; and a similar looking fish, Hyphessobrycon togoi largely replaces it here. The type locality is Villarrica in Guairá Department, central Paraguay. In the wild, they are commonly found in rivers, ponds, lakes, and streams. They are a freshwater fish, and do not do well in conditions that may offer too salty or too filthy water. They swim in schools and are a social fish, always together with their own kind.
The tetra is a tropical, silver metallic-colored fish, with red-tipped fins and a black marking on the dorsal fin. The tetra is a hardy community fish for beginners, and is optimal for the beginning fish hobbyist. [4] It is also relatively large for a tetra, growing up to 7.5 cm (3 inches). [4] They can live up to 5 or 6 years. Its silver color picks up flashy neon highlights depending on how the light hits the fish. The top and bottom of the tail fin is generally red, along with the pelvic and anal fins. The dorsal fin may also have a hint of red at the very tip. Its most distinguishing characteristic is the caudal peduncle, or the connecting area between the tail and the rest of the body, which features a bold, black 'cross' shape. [4]
The Buenos Aires tetra are very durable, and do not have any special needs or requirements. A maintained freshwater tank and food is all that they really need. However, they are hearty feeders that must be well-fed or they may begin to nip at their long-finned tank-mates. Keeping the tetras in a school of 5 or more definitely decreases aggression. This species can occasionally nip at and eat aquarium plants. [4]
Buenos Aires tetras are an omnivorous species. In the wild they feed on worms, crustaceans, insects, and plants, but in the aquarium they will generally eat all kinds of live, fresh, and flake foods. To keep a good balance, give them a high quality flake food every day. To keep these tetras at their best and most colorful, offer regular meals of live and frozen foods, such as bloodworms, Daphnia , and brine shrimp. Vegetables should also be added to their diet. Feed these tetras several times a day and only what they can consume in 3 minutes or less at each feeding. [4]
Buenos Aires tetras breed occasionally in an aquarium setting. They breed by scattering their eggs into their environment, [5] hoping that they will be fertilized and lead to young. When breeding does occur, a hospital or "breeding tank" will be necessary. For optimal breeding conditions, use slightly acidic water. Much like most other species of fish, once the eggs begin to hatch, removing the parents will reduce the number of lost fry, as the parents will soon begin to eat their young. [6] Once the eggs are laid, the fry will begin to hatch in about 24 hours. For the next three or four days, they will eat their egg sac and then become free swimming fry. [5]
The neon tetra is a freshwater fish of the characin family of order Characiformes. The type species of its genus, it is native to blackwater and clearwater streams in the Amazon basin of South America. Its bright colouring makes the fish visible to conspecifics in the dark blackwater streams, and is also the main reason for its popularity among freshwater fish hobbyists, with neon tetras being one of the most widely kept tropical fish in the world.
The black tetra, also known as the black skirt tetra, petticoat tetra, high-fin black skirt tetra, black widow tetra and blackamoor, is a freshwater fish of the characin family (Characidae).
Tetra is the common name of many small freshwater characiform fishes. Tetras come from Africa, Central America, and South America, belonging to the biological family Characidae and to its former subfamilies Alestidae and Lebiasinidae. The Characidae are distinguished from other fish by the presence of a small adipose fin between the dorsal and caudal fins. Many of these, such as the neon tetra, are brightly colored and easy to keep in captivity. Consequently, they are extremely popular for home aquaria.
The black neon tetra is a freshwater fish of the characin family (Characidae) of the order Characiformes. It is native to the Paraguay basin of southern Brazil. They are often found in the aquarium trade.
The black phantom tetra, or simply phantom tetra, is a small freshwater fish of the characin family (Characidae) of order Characiformes. It is native to the upper Paraguay basin and upper Madeira basin in Brazil and Bolivia. It is commonly seen in the aquarium trade.
The serpae tetra, also known as the red minor tetra, jewel tetra or callistus tetra, is a species of tetra, a tropical freshwater fish of the characin family of order Characiformes. It is native to the Amazon River drainage in Brazil, Peru, Paraguay, Bolivia and northern Argentina. The fish can be found in slow moving or still backwater including, ponds, small lakes, and streams. In the wild, it forms aggregations around vegetation and tree roots, and thrives when the water temperature is 22–27 °C (72–81 °F).
The lemon tetra is a species of tropical freshwater fish which originates from South America, belonging to the family Characidae. It is a small tetra growing to 5 cm (2 in) in length. The species is a long established favourite aquarium fish, being introduced to the aquarium in 1932.
The rummy-nose tetra is a species of tropical freshwater characin fish originating in South America, popular among fishkeepers as a tropical aquarium fish. One of many small tetras belonging to the same genus, it is on average 5 cm (2 in) long when fully grown. The fish is one of several very similar species including Petitella bleheri, and Petitella georgiae, and it is possible that more recently collected specimens available in the aquarium trade are members of one or other of these similar species. The common name applied to most of these fishes is "rummy-nose tetra", though other common names are in circulation.
The bloodfin tetra is a species of characin from the Paraná River basin in South America. The bloodfin is a relatively large tetra, growing to 5.5 cm. Its notable feature is the blood-red colouration of the tail, dorsal, anal and adipose fin, while the body is silver in color.
Hemigrammus erythrozonus, commonly known as the glowlight tetra, is a small tropical fish from the Essequibo River, Guyana, South America. It is silver in colour and a bright iridescent orange to red stripe extends from the snout to the base of its tail, the front of the dorsal fin being the same color as the stripe. Other fins are silver to transparent. The glowlight tetra is a peaceful, shoaling fish. It is larger than the neon tetra, and its peaceful disposition makes it an ideal, and popular, community tank fish. It should be kept with similar sized, non-aggressive species. Hemigrammus gracilis is a senior synonym. The red-line rasbora of Malaysia and Indonesia has markings and coloring very similar to H. erythrozonus, but is a member of family Cyprinidae, not a close relative.
Hyphessobrycon columbianus is a species of Tropical freshwater fish of the characin family. The Colombian tetra is native to the Acandi River near Acandí) in northwestern Colombia. The Colombian tetra's habitat tends to be slow-flowing creeks and tributaries.
The diamond tetra is a small freshwater fish of the characin family of order Characiformes. It is found in and around Lake Valencia in Venezuela, South America.
The redeye tetra, is a species of tetra from the São Francisco, upper Paraná, Paraguay and Uruguay river basins in eastern and central South America. This freshwater fish is commonly kept in aquariums and bred in large numbers at commercial facilities in Eastern Europe and Asia. The redeye tetra is one of the more popular aquarium fish due to their schooling capability.
The snakeskin gourami is a species of gourami native to Southeast Asia. Prior to the merging of Belontidae to the family Osphronemidae, the snakeskin gourami was regarded as the largest member of its family. It is still the largest species in its genus and subfamily.
The rainbow shark is a species of Southeast Asian freshwater fish from the family Cyprinidae. It is also known as the ruby shark, red-fin shark, red-finned shark, rainbow sharkminnow, green fringelip labeo, whitefin shark and whitetail sharkminnow. It is a popular, semi-aggressive aquarium fish. Unlike true sharks, which belong to the Chondrichthyes lineage, the rainbow shark is an actinopterygiian.
The ember tetra is a freshwater fish of the characin family of order Characiformes. It is native to the Araguaia River basin of Brazil and was discovered in 1987 and named in honor of the fish explorer Heiko Bleher's mother.
The White Cloud Mountain minnow is a hardy species of freshwater fish and coldwater fish often kept in an aquarium. The species is a member of the carp family of the order Cypriniformes, native to China. The White Cloud Mountain minnow is practically extinct in its native habitat, due to pollution and tourism. It was believed to be extinct for over 20 years in 1980, but an apparently native population of this fish was discovered on Hainan Island, well away from the White Cloud Mountain. They are bred in farms and are easily available through the aquarium trade. However, inbreeding in farms has led to genetically weak stock that is vulnerable to disease and prone to physical deformities.
Hyphessobrycon sweglesi is a species of tetra that lives in the Orinoco River drainage basin in South America. The species' scientific name used to be Megalamphodus sweglisi and the species' common name is red phantom tetra. It grows up to 4 cm (1.6 in).
Hyphessobrycon heterorhabdus, commonly known as the flag tetra or Belgian flag tetra, is a species of freshwater characin fish endemic to Brazil. Belonging to the family Characidae, this species is distinguished by its vibrant coloration and patterns, which have contributed to its popularity in the aquarium trade.
The yellow-tailed African tetra is a freshwater fish that lives in the Congo River basin. It is found in both the Democratic Republic of the Congo and the Republic of the Congo. It is an omnivore in the wild which feeds on crustaceans, fallen fruits and small insects, but seems to have little difficulty in adjusting to normal aquarium foods. though they can be fed in aquarium with daphnia, bloostorm and artemia along good quality dried flakes and granules at least some of which should include additional plant or algal content. The species can tolerate water up to 20 degrees DH, though it does better in softer water. A temperature of 22–26 °C (72–79 °F) and a pH of between 5.0 and 7.5 and a hardness of between 36 and 268ppm is suitable. adult male are more colorful and tend to grow faster than females. males also develops extended white-tipped dorsal, ventral, caudal and anal fins which females lack. it is an egg scattered exhibiting no parental care, and one method of breeding is apparently to keep a group of adults in their own aquarium furnished with a kind of artificial trap, checking it regularly as much as possible especially for eggs. these are removed and normally hatched in smaller containers with the fry being offered microscopic foods until large enough to accept daphnia, bloostorm and the rest.
