The blue danio, Kerr's danio or turquoise danio (Danio kerri), is a tropical fish belonging to the genus Danio in family Cyprinidae.
The blue danio is found on the islands of Langkawi and Ko Yao Yai in Malaysia.[ citation needed ]
It is a blue-colored, deep-bodied danio with several pinkish/gold lines from tail to gills which may or may not be continuous, over a powder blue side.
The blue danio is a peaceful, active schooling fish, so is usually kept in groups. They prefer a well-planted environment, but still need plenty of space to school. Blue danios are often kept in water with a 6.5 – 7.0 pH, a water hardness of 8 – 12 dGH, and a temperature range of 73 – 77 °F (23–25 °C).
Blue danios are egg-scatterers that spawn over coarse gravel beds. They will typically spawn at the first light of day.[ citation needed ] The eggs will hatch in about 36 hours.
The taxonomic name honors A.F.G. Kerr, who collected the first specimen on Ko Yao Yai in 1929.
The white bass, silver bass, or sand bass is a freshwater fish of the temperate bass family Moronidae. commonly around 12-15 inches long. The species' main color is silver-white to pale green. Its back is dark, with white sides and belly, and with narrow dark stripes running lengthwise on its sides. It has large, rough scales and two dorsal fins. They are widely distributed across North America, inhabiting large reservoirs and rivers. When mating in the spring, they are more often found in shallow rivers, creeks, and streams. They have been introduced in some places as sport fish and also to predate on nuisance fish, such as gizzard shad. It is the state fish of Oklahoma.
The tiger barb or Sumatra barb, is a species of tropical cyprinid fish. The natural geographic range reportedly extends throughout the Malay Peninsula, Sumatra and Borneo in Indonesia, with unsubstantiated sightings reported in Cambodia. Tiger barbs are also found in many other parts of Asia, and with little reliable collection data over long periods of time, definite conclusions about their natural geographic range versus established introductions are difficult. Tiger barbs may sometimes be confused with Puntigrus anchisporus, Puntigrus navjotsodhii, or Puntigrus partipentazona, which are similar in appearance, the only differences being the slightly different stripe pattern and the number of scales these fish have.
The giant danio is a tropical fish belonging to the minnow family Cyprinidae. Originating in Sri Lanka, Nepal, and the west coast of India, this species grows to a maximum length of 4-6 inches (10-15 cm), making it one of the largest of the danionins. It is characterized by a blue and yellow, torpedo-shaped body with gray and clear fins.
The pearl danio is a tropical fish belonging to the minnow family Cyprinidae. Originating in Sumatra, Myanmar, and Thailand, this fish is sometimes found in aquariums by fish-keeping hobbyists. It grows to a maximum length of 2.6 inches (6.5 cm) and lives for around five years. The fish could have a brownish-yellow, pink, or a silver body and two light yellow/white or blue/red stripes. It has an iridescent look. The female fish has two pairs of barbels.
Labidochromis caeruleus is a species of cichlid endemic to the central western coastal region of Lake Malawi in East Africa. It is also known as lemon yellow lab, the blue streak hap, the electric yellow or yellow prince, depending on the colour morph. A naturally occurring yellow-coloured variant from Lion's Cove is one of the most popular cichlids amongst aquarium hobbyists.
The spotted danio or dwarf danio is a tropical fish belonging to the minnow family (Cyprinidae). Originating in northern Myanmar, this fish is sometimes found in community tanks by fish-keeping hobbyists. It grows to a maximum length of 1.5 inches (3.7 cm).
The Malabar danio is a tropical fish belonging to the minnow family (Cyprinidae). Originating in Sri Lanka and the west coast of India, the fish has been circulated throughout the world through the aquarium fish trade. It grows to a maximum length of 6 in (15 cm) rarely exceeds 4 in (10 cm) in a home aquarium.
The paradise fish, paradise-fish, paradisefish, or paradise gourami is a species of gourami found in most types of fresh water in East Asia, ranging from the Korean Peninsula to northern Vietnam. This species can reach a standard length of 6.7 cm, though most are only about 5.5 cm . Paradise gouramis were one of the first ornamental fish available to western aquarium keepers, having been imported 1869 to France by the French aquarium fish importer Pierre Carbonnier in Paris. The paradise fish is one of the more aggressive members of its family. It is more aggressive than the three spot gourami, yet less pugnacious in nature than the less commonly kept combtail.
The dwarf gourami is a species of gourami native to South Asia.
The harlequin rasbora is a small fish in the family Cyprinidae. The species became an instant favorite among aquarists after its introduction in the early 1900s and is the best known and most widely kept species among the rasboras. In 1935, an image of a trio of harlequin rasboras, stamped in 14k gold, would grace the cover of the first edition of William T. Innes's classic Exotic Aquarium Fishes and would remain so through all 19 editions.
Danio is a genus of small freshwater fish in the family Cyprinidae found in South and Southeast Asia, commonly kept in aquaria. They are generally characterised by a pattern of horizontal stripes, rows of spots or vertical bars. Some species have two pairs of long barbels. Species of this genus consume various small aquatic insects, crustaceans and worms.
Corydoras paleatus is a species of catfish of the family Callichthyidae. Its common names include blue leopard corydoras, mottled corydoras, and peppered catfish. It originates from the lower Paraná River basin and coastal rivers in Uruguay and Brazil.
The pygmy gourami, also known as the sparkling gourami, is a freshwater species of gourami native to Southeast Asia.
The dwarf corydoras, dwarf catfish, tail spot pygmy catfish, or micro catfish is a tropical freshwater fish belonging to the subfamily Corydoradinae of the family Callichthyidae. It originates in inland waters in South America, and is found in the Amazon River and Paraguay River basins in Argentina, Bolivia, and Brazil. The specific epithet hastatus means with a spear, in reference to the spearhead-like spot on the tail root.
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.
Danio margaritatus, the celestial pearl danio, often referred to in the aquarium trade as galaxy rasbora or Microrasbora sp. 'Galaxy', is a small cyprinid from Myanmar. It has so far been found only in a very small area near Hopong east of Inle Lake, at an elevation of over 1,000 m (3,400 ft). Its habitat is part of the Salween basin, namely the Nam Lang and Nam Pawn Rivers. Discovered in 2006, the species quickly appeared in the aquarium trade, where its small size and bright colours made it an instant hit.
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 violet goby is a species of goby native to marine, fresh and brackish waters near the Atlantic coast of North and South America from South Carolina in the United States of America, to northern Brazil. It prefers bays, estuaries and river mouths with muddy substrates. It is often marketed as the dragon goby or dragon fish.
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.
The Odessa barb is a species of cyprinid fish known from Central Myanmar, where it is known to occur in an artificial pond above the Anisakan Falls and also from the lower Chindwin River. For many years it has been known to the aquarium hobby, where it has frequently been confused with the less colourful ticto barb), but it was only described scientifically in 2008.
