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 cardinal tetra is a freshwater fish of the family Characidae of order Characiformes. It is native to the upper Orinoco and Negro Rivers in South America. Growing to about 3 cm (1.2 in) total length, the cardinal tetra has the striking iridescent blue line characteristic of the genus Paracheirodon laterally bisecting the fish, with the body below this line being vivid red in color, hence the name "cardinal tetra". The cardinal tetra's appearance is similar to that of the closely related neon tetra, with which it is often confused; the neon's red coloration extends only about halfway to the nose, and the neon's blue stripe is a less vibrant blue.
The Denison barb, Denison's barb, Miss Kerala, red-line torpedo barb, or roseline shark is an endangered species of cyprinid fish endemic to the fast-flowing hill streams and rivers of the Western Ghats in India. It is commonly seen in the aquarium trade; pet collection caused it to become endangered and is its single major threat.
The elongate glassy perchlet is a species of freshwater fish in the Asiatic glassfish family Ambassidae of order Perciformes, the only species in the genus Chanda. It is native to an area of south Asia from Pakistan to Burma, in the Indomalayan realm.
Parambassis is a genus of freshwater fish in the Asiatic glassfish family Ambassidae of order Perciformes. The type species is the Iridescent glassy perchlet. These fishes originate mostly from Southeast Asia, but the species range across the Indomalayan and Australasian realms, from Pakistan, China and India south through Indonesia, New Guinea and Australia. Although primiarly found in fresh water, a few species can also be seen in brackish water. The Parambassis species range in maximum size from 4–24 cm (1.5–9.5 in), but they are similar in appearance, with a lozenge-shaped form, typical perciform fins, and semitransparent or transparent body. Several of the species are common food fish in local markets, and some are kept as aquarium fish.
The reedfish, ropefish, or snakefish, Erpetoichthys calabaricus, is a species of fish in the bichir family and order. It is the only member of the genus Erpetoichthys. It is native to fresh and brackish waters in West and Central Africa. The reedfish possesses a pair of lungs in addition to gills, allowing it to survive in very oxygen-poor water. It is threatened by habitat loss through palm oil plantations, other agriculture, deforestation, and urban development.
Painted fish are ornamental aquarium fish which have been artificially coloured to appeal to consumers. This artificial colouring, also known as juicing, is achieved by a number of methods, such as injecting the fish with a hypodermic syringe containing bright fluorescent colour dye, dipping the fish into a dye solution, or feeding the fish dyed food.
Fishkeeping is a popular hobby, practiced by aquarists, concerned with keeping fish in a home aquarium or garden pond. There is also a piscicultural fishkeeping industry, serving as a branch of agriculture.
Xenentodon cancila, the freshwater garfish, is a species of needlefish found in freshwater and brackish habitats in South and Southeast Asia.
The salt and pepper catfish is a tropical freshwater fish belonging to the Corydoradinae sub-family of the family Callichthyidae. It originates in inland waters in South America, and is found in the Upper Orinoco River basin in Venezuela and Colombia.
The keyhole cichlid is a cichlid fish endemic to tropical South America, occurring in the lower Orinoco Basin in Venezuela and river basins in The Guianas. It is the only species in the genus Cleithracara. The species is popular with fishkeeping hobbyists and is frequently kept in aquariums.
The dwarf pufferfish, also known as the Malabar pufferfish, pygmy pufferfish, or pea pufferfish, is a small freshwater pufferfish endemic to Kerala and southern Karnataka in Southwest India. They are popular in aquaria for their bright colours and small size. At a maximum length of 3.5 cm, dwarf pufferfish are one of the smallest pufferfish in the world. They closely resemble the related Carinotetraodon imitator, and the two can be difficult to distinguish. C. imitator was not recognised as a different species until 1999.
A brackish-water aquarium is an aquarium where the water is brackish (semi-salty). The range of "saltiness" varies greatly, from near freshwater to near marine and is often referred to as specific gravity (SG) or salinity. Brackish water aquaria is a popular specialization within the fishkeeping hobby. Many species of fish traded as freshwater species are actually true brackish species, for example mollies, Florida flagfish, and some cichlids such as chromides and black-chin tilapia. There are also several popular species traded purely as brackish water fish, including monos spp, scats, archerfish, and various species of pufferfish, goby, flatfish, and gar. Generally, aquarists need to maintain a specific gravity of around 1.005 to 1.010 depending on the species being kept, but practically all brackish water fish tolerate variations in salinity well, and some aquarists maintain that regularly fluctuating the salinity in the aquarium actually keeps the fish healthy and free of parasites.
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.
Farlowella acus is the type species of the armored catfish genus Farlowella, which are commonly known as the twig catfish or whiptail catfish. The species name means “pointed” or a “needle” or “spine”.
The glassy sprat is a type of sprat fish. The fish, when alive, is translucent, so it gets the second word in its scientific name from the Latin word translucidus, meaning transparent, diaphanous. In animal classification the glassy sprat belongs to Osteichthyes, Clupeiformes, Clupeidae, Hyperlophus. The glassy sprat is native to Australia and mainly found in Australia. It is marked as NE because it has not yet been evaluated by the World Animal Protection. It is mainly used as an economical aquatic product. In ecosystems, they are at the bottom end of the food chain, feeding mainly on plankton, which are less aggressive and very vulnerable to other fish. Glassy sprat are tiny in size and translucent with a silvery streak that extends from its tail to just behind its head. As early as a hundred years ago, Australians harvested the glassy sprat in large quantities and it featured on the table as food for a long time. Due to its poor appearance, it is not a very good ornamental fish.
The Siamese tigerfish, also known as the Siamese tiger perch, is a critically endangered Asian fish native to the Chao Phraya, Mae Klong and Mekong basins. It has vertical yellow and black stripes running the length of its body. The dorsal fin has a spiny appearance. Siamese tigerfish grow to 40 cm (16 in) in standard length.
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.
Zenarchopteridae, the viviparous halfbeaks, is a family in the order Beloniformes. The Zenarchopteridae exhibit strong sexual dimorphism, practicing internal fertilisation, and in some cases ovoviviparous or viviparous. The members in the family are mainly found in fresh and brackish water of tropical Asia and New Guinea, but the genus Zenarchopterus also includes marine species from the Indo-Pacific. Several, such as the wrestling halfbeak, have become commonly traded aquarium fish.
Parambassis pulcinella, the humphead glassfish or humphead perchlet, is a species of Asiatic glassfish native to fast-flowing streams in the Ataran basin in southeast Myanmar and west Thailand. It reaches a length of 10 cm (3.9 in) and is sometimes seen in the aquarium trade. It is a relative of the perch.
