It prefers areas in the lakes that are near to river outlets This species grows to a length of 20 centimetres (7.9 in) TL. It can also be found in the aquarium trade.

Nimbochromis livingstonii, Livingston's cichlid or (locally) kalingono, is a freshwater mouthbrooding cichlid native to Lake Malawi, an African Rift Lake. It is also found in the upper Shire River and Lake Malombe. They are found in inshore areas of the lake over sandy substrates.

Otopharynx tetrastigma is a species of cichlid native to Lake Malawi, Lake Malombe and the upper reaches of the Shire River. This species can reach a length of 16 centimetres (6.3 in) TL. It can also be found in the aquarium trade.

The Penang betta is a species of gourami native to Southeast Asia and common in swiftly flowing forest streams of the Malay Peninsula, Thailand, Sumatra, and the Riau Islands. In addition to its native range, the species has been introduced to Guam. It can be found amongst the vegetation growing along the banks. This species can reach a length of 6.7 centimetres (2.6 in) SL. It is one of the mouthbrooding Betta species. This species, as a natural predator of mosquito larvae, has found use in mosquito control efforts. Prior to its being eclipsed in Western public recognition by the mass-imported B. splendens, B. pugnax was well known as a fighting fish, as denoted by the specific epithet of pugnax, attracting the interest of scientists studying animal behaviour at least as long ago as the 1880s.

Placidochromis johnstoni is a species of cichlid native to Lake Malawi, Lake Malombe and the upper reaches of the Shire River where it prefers shallow waters with plentiful vegetation. This species can reach a length of 20 centimetres (7.9 in) TL. It can also be found in the aquarium trade. The specific name honours the British explorer, botanist, artist, colonial administrator and linguist Sir Henry Hamilton Johnston, better known as Harry Johnston, who collected the type and sent it to the British Museum.

The plateau chub is an extinct species of ray-finned fish in the family Cyprinidae. It was found only in Mexico.

Poecilia parae is a species of fish from the family Poeciliidae which is found in northern South America from Guyana to the mouth of the Amazon River.

Pristella maxillaris, the only species in the genus Pristella, is commonly known as the X-ray fish or X-ray tetra because of its translucent body. It is a widely distributed and adaptable fish, found in the Amazon and Orinoco basins, as well as coastal rivers in the Guianas in both acidic and alkaline waters. Unlike most other characins, it is tolerant of slightly brackish water. It is small and lives in large groups, and males can be distinguished from females by being smaller and thinner than the females. Like most other tetras, it feeds primarily on small insects and planktonic animals.

Protomelas kirkii is a species of cichlid endemic to Lake Malawi where it is most commonly found in areas vegetated with Vallisneria. This species can reach a length of 18 centimetres (7.1 in) TL. This species can also be found in the aquarium trade.

The red top williamsi is a species of cichlid endemic to Lake Malawi where it occurs in areas with rocky substrates usually at depths of less than 2 metres (6.6 ft). This species can reach a length of 16.5 centimetres (6.5 in) TL. It can also be found in the aquarium trade. The specific name honours the Anglican missionary Joseph A. Williams who died by drowning in Lake Malawi in 1895, with Bishop Chauncy Maples, and who collected the type of the cichlid among others.

The redfin bully is a species of freshwater fish in the family Eleotridae endemic to New Zealand. Being amphidromous, it spends part of its life cycle at sea. Males have distinctive bright red patterns and stripes on their fins. Adults grow to an average of 80–100 mm (3.1–3.9 in) total length, with a maximum of 120 mm (4.7 in).

The reticulate sculpin is a species of fish in the family Cottidae. It is found in the United States, inhabiting Pacific Slope drainages from the Snohomish River and Puget Sound in Washington to the Rogue River system in Oregon and California. It reaches a maximum length of 10.0 cm. This sculpin occurs in a variety of habitats, but mainly occurs in the slower sections of coastal headwaters, creeks, and small rivers. It prefers faster water with rubble or gravel substrate, but occurs in pools and along stream edges when other sculpin species are present. Often it occurs in clear cold water in forested areas. It's ideal habitat is cold creeks in old-growth forest, with plenty of riffles and runs. This species is tolerant of variable water temperatures and salinities. Where other sculpin species are common, spawning occurs in slow-flowing areas; where other sculpin species are rare or absent, spawning usually occurs in riffles.

Sebastes dallii is a species of fish in the rockfish family in the Eastern central Pacific. It is commonly known as the calico rockfish.

Stigmatochromis modestus is a species of cichlid endemic to Lake Malawi where it lives among rocks. It is an ambush predator, feeding on other fishes. It can reach a length of 25 centimetres (9.8 in) TL. It can also be found in the aquarium trade.

Umatilla dace is a species of ray-finned fish in the genus Rhinichthys. It is found in the dariange basin of the Columbia River in British Columbia, Washington state, Oregon and Idaho.

The Wood River sculpin is a species of fish in the family Cottidae. It is endemic to the Big Wood and Little Wood rivers and their tributaries upstream of Magic Reservoir in Blaine County, Idaho in the United States. Its habitat is similar to other sculpins: small to medium-sized streams that are cool and have swift currents. It is a species of concern because of its restricted distribution.
