THE Senegal bichir (Polypterus senegalus) also known as the gray bichir and Cuvier's bichir, is sometimes called the "dinosaur eel" (a misnomer, as the creature is neither an eel nor a dinosaur) also called "Dinosaur Bichir" or "dragon fish" in the pet trade. It is a prototypical species of fish in the genus Polypterus, meaning most of its features are held across the genus. Commonly kept in captivity by hobbyists. They are native from Africa where they are the most widespread species of the genus.

name upside-down catfish is most commonly used by aquarists to refer to the mochokid catfishSynodontis nigriventris alternately known to ichthyologists as the blotched upside-down catfish or false upside-down catfish.However, a number of other fish may also be known by this name: Mystus leucophasis – Asian upside-down catfish Synodontis angelicus – spotted upside-down catfish Synodontis aterrima – sometimes sold as S. nigriventris in the aquarium trade, but in the past not identified as a separate species by retailers Synodontis batensoda=Brachysynodontis batensoda– known as giant upside-down catfish, or squeaker. Found in northern, northeast, and western Africa Synodontis contracta – big-nosed upside-down catfish, sometimes sold as S. nigriventris to aquarists, a species with which it is easily confused Synodontis nigrita – false upside-down catfish, very commonly sold as S. nigriventris in the aquarium trade and only recognised as a different species once the fish matures (adults are more than twice the size of adult S. nigriventris) The name 'dwarf upside-down catfish' is also used for small (around 10 cm) species of the catfish genus Synodontis. In the aquarium trade, the name is almost always applied to S. nigriventris or species with which it may be confused, such as S. aterrima, S. contracta, and juvenile S. nigrita (adults of which are around 20 cm so are not "dwarf" species at all) As its common name implies, the upside-down catfish will swim upside-down. One theory accounts for this unusual behavior as a feeding strategy. In the wild, it often grazes on the undersides of submerged branches and logs, and swimming upside-down makes these areas more accessible. A different theory suggests swimming upside-down makes aquatic surface respiration more efficient.
Peacock bass (Cichla) is a genus of large cichlids, diurnal and predatory freshwater fish native to the Amazon and Orinoco basins, as well as rivers of the Guianas, in tropical South America.They are sometimes referred to in English by their Brazilian name tucunaré or their Spanish name pavon.Despite the common name and their superficial similarity, they are not closely related to other fish known as bass, such as the North American largemouth bass (Micropterus salmoides).

Paratilapia polleni is a medium-sized cichlid endemic to Madagascar. It is also a popular fish for display at public aquaria. It is sometimes referred to by the common names polleni cichlid and black diamond cichlid, while the name marakely is used among locals in Madagascar.
Toxotes blythii, the clouded archerfish or zebra archerfish, is a perciform fish of genus Toxotes. It is in rivers and estuaries in Myanmar, ranging from the lower Irrawaddy to the Tenasserim Division, including lower Sittaung and Salween.[Unlike some other archerfish, it is restricted to fresh water.This species was formerly thought to be identical to T. microlepis (smallscale archerfish). However, differences in structure and colouration caused the splitting of T. blythii into a new species.It is sometimes seen in the aquarium trade, but is generally rare. Toxotes blythii
