Danio tinwini

Danio tinwini, commonly called gold-ring danio, is a newly discovered species of Danio from Myanmar. It is also referred to as Danio sp. "TW02". It is a tiny gold fish whose body and fins are covered with blue spots. It has also been referred to as Danio sp "Ringlet" or Danio sp "Blue Ring". It has been described by Kullander and Fang, [1] based on collection by Mr U Tin Win, hence its species name. It is known only from the Mogaung Chaung (Mogaung stream), Myitkyina District, Kachin State, northern Myanmar. This is a tributary of the Irrawaddy River.

It is similar to D. kyathit and D. nigrofasciatus, but can be differentiated by its smaller size, spotted (vs. striped) patterning in the unpaired fins, and much shorter barbels.

Pearl danio Species of fish

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.

<i>Devario</i> Genus of fishes

Devario is a genus of fish in the family Cyprinidae native to the rivers and streams of South and Southeast Asia. These fishes have short barbels and many species having vertical or horizontal stripes. These species consume various small, aquatic insects, crustaceans and worms, as well as, in the case of fry, plankton.

Glowlight danio Species of fish

The glowlight danio is a small, schooling fish closely related to the popular zebrafish Danio rerio. This should not be confused with the GloFish, a trademarked brand of fluorescent zebrafish that appear to glow in the dark under ultraviolet light. Danio choprae is an active danionin species that spends most of its time on mid-water levels. This species feeds on insects that have fallen into the water, aquatic insect larvae, and other small animals. In the aquarium, it accepts most foods offered, including most dry foods. It has a streamlined body marked with a brilliant orange longitudinal band and a series of vertical blue-black bars on the flanks. The fins are edged with yellow. In recent years, it has become quite widely traded as an aquarium fish, but otherwise has no commercial importance. Its common name derives from its similarity to the glowlight tetra, a South American characin only distantly related to this fish. They get on well with all other Danio species except the giant danio.

The Hikari danio is a new species of danio recently discovered in Burma, and first exported in 2002/2003. It is still awaiting a scientific name, and is temporarily referred to as Danio sp. "Hikari". It has blue and yellow varieties with the yellow being male and the blue female. It appears to be closely related to Danio kerri. It may be a subspecies of this fish, but this does not seem to be the case.

<i>Microrasbora</i> Genus of fishes

Microrasbora is a genus of small fishes. The generic name means "small Rasbora", however these are more closely related to the danios than rasboras. They inhabit freshwater in Myanmar and Yunnan, China.

Rose danio Species of fish

The rose danio is a tropical fish of the family Cyprinidae. At first glance, this species resembles the pearl danio, but lacks the orange stripe on the side. It has a rosy colouration along the lower part of the fish and lower fins and gleams purple-blue in sunlight. It is also commonly known as the purple passion danio. Its natural range includes the Mekong River drainage in China, Thailand. Laos, and Myanmar.

<i>Danio kyathit</i> Species of fish

Danio kyathit is a small, schooling species of fish in the family Cyprinidae. It is endemic to the upper reaches of Irrawaddy River near Myitkyina in northern Myanmar. Described in 1998, it is closely related to the better-known zebrafish or zebra danio, D. rerio.

The blue moon danio is a species of cyprinid fish endemic to Myanmar. First described in 2009, they are found in small forested streams on the western slope of the Arakan Mountains in Rakhine State of south-western Myanmar; these streams are typically reduced to a series of interconnected pools during the dry season. This species has also been imported to Europe as an aquarium fish with the code names “TW02” and “Broken Line”.

Coldwater fish

Coldwater fish, in the context of aquariums, refers to fish species that do not require a heater to remain within tolerable temperatures in a typical indoor aquarium. Some examples are koi, goldfish, weather loaches, hillstream loaches, many species of barbs, sunfish of the family Centrarchidae, many Central American cichlids, and a variety of other species. Some, but not all, of these species are capable of surviving in very low temperatures, including ponds, lakes, or rivers that freeze over winter.

<i>Danio</i> Genus of fishes

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.

Indian flying barb Species of fish

The Indian flying barb, historically flying barb, is one of the species known in the group flying barbs owing to their extremely long barbels. It was discovered as long ago as 1822 by Hamilton. However, it is rarely seen in aquaria. It is found in Myanmar, Nepal, Pakistan, Sri Lanka and India, it is found in many of the same localities as Danio rerio and Danio dangila, an example being the Jorai Rivulet, a tributary of the Sankosh river in Coochbehar district, West Bengal, India. The rare fish Borellius spp. is locally named "Boirali maach".

<i>Danio margaritatus</i> Species of fish

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 dracula fish is a species of tropical danionin fish from the cyprinid family. It is a freshwater fish endemic to Myanmar. A close relative is Danio rerio, the zebrafish of aquariums. It is named dracula after its unusual "fangs"; male dracula fish have protruding tooth-like bones stemming from their jawbones. Males have been observed using their fangs to spar with other males.

Danionin Subfamily of fishes

The danionins are a group of small, minnow-type fish belonging to the family Cyprinidae. Members of this group are mostly in the genera Danio, Devario, and Rasbora. They are primarily native to the fresh waters of South and Southeast Asia, with fewer species in Africa. Many species are brightly coloured and are available as aquarium fish worldwide. Danio species tend to have horizontal stripes, rows of spots, or vertical bars, and often have long barbels. Devario species tend to have vertical or horizontal bars, and short, rudimentary barbels, if present at all. All danionins are egg scatterers, and breed in the rainy season in the wild. They are carnivores, living on insects and small crustaceans.

Danio annulosus is a species of Chain danio fish in the family Cyprinidae in Danio genus. The species is named and described jointly by Sven O Kullander, M.D Mizanur Rahman, Michael Noren and Abdur Rob Mollah in 2015 in association with the Department of Zoology, Swedish Museum of Natural History, Sweden and the Department of Zoology, University of Dhaka, Bangladesh. The study and paper on Danio annulosus was published in ZooTaxa both online and in print in the same year (2015). It was collected from a small pool at the bottom of the Shuvolong Falls in the Kaptai Lake system in Rangamati district in the Chittagong division, Bangladesh. The species name annulosus is derived from the neo-Latin word meaning "ringed", from the color pattern on the side of the fish which resembles a pattern of dark rings.

Red dwarf rasbora Species of fish

Red dwarf rasbora is a species of cyprinid found endemic to Lake Inle in Shan State in Myanmar. It belongs to the genus Microrasbora, which contains two small species of danionins.

Devario fangae is a species of small cyprinid fish, a type of danio which was described by the Swedish ichthyologist Sven Kullander in 2017 from specimens collected in previous years in from small streams which drained into the Mali River, a tributary of the Ayeyarwaddy River in the area around Putao in the extreme north of Kachin State in Myanmar. It appears to be closely related to Devario browni and to D. kakhienensis but is distinguished from them by the dark stripe along the middle of the side of the body being wider than the adjacent paler coloured stripes on either side. The specific name is in memory of the late Fang Fang Kullander (1962-2010), who collected the first specimens and who suggested they may represent a new species in honour of her contribution to knowledge of the freshwater fish fauna of Myanmar.

Fang Fang Kullander, née Fang Fang, was a Swedish-Chinese ichthyologist.
