Chondrostoma soetta, or the Italian nase, is a species of freshwater fish in the family Cyprinidae. It is found in Italy, Slovenia, and Switzerland. Its natural habitats are rivers and freshwater lakes. It is threatened by habitat loss and predation and competition from introduced species such as roach, wels catfish and the common nase. It has been extirpated from Slovenia and numbers are declining in the Italian and Swiss lakes of Lake Como, Lake Lugano, Lake Maggiore, Lake Iseo and Lake Garda. Some population which are descended from fish introduced to other lakes in Italy appear to be thriving.

Its natural habitats are rivers, intermittent rivers, and freshwater springs. It is threatened by habitat loss. Ladigesocypris irideus is the other member of the genus according to Fishbase.

The Lake Rukwa lampeye is a species of fish in the family Poeciliidae. Its natural habitats are intermittent rivers, freshwater marshes, and intermittent freshwater marshes. It is threatened by habitat loss. This species occurs in central Africa in Lake Rukwa, Tanzania, the Malagarasi River, Wembere River system and the upper basin of the Congo River. Its specific name honours the German physician and zoologist Friedrich Fülleborn (1866-1933), who collected the type.
Pachypanchax omalonotus, the powder-blue panchax, is a species of Aplocheilid killifish endemic to Madagascar where it is found on the island of Nosy Be and in the Sambirano River basin and adjacent streams on the mainland. Its natural habitat is rivers.
Pachypanchax sparksorum is a species of Aplocheilid killifish endemic to Madagascar where it is found in the Anjingo River and streams feeding into the Ankofia River. Its natural habitat is rivers. The specific name of this fish honours the ichthyologist John S. Sparks of the United States National Museum and his wife Karen Riseng Sparks, they collected many of the type series.
Pachypanchax arnoulti is a species of aplocheilid killifish endemic to Madagascar. Its natural habitat is rivers and lakes. It is threatened by habitat loss and invasive species. The specific name of this fish honours the French ichthyologist and herpetologist Jacques Arnoult (1914-1995) in recognition of his contributions to the knowledge of Madagascar's fish fauna. It was described by Paul V. Loiselle in 2006 with the type locality given as "Swamp draining into tributary stream of Ikopa River, flowing parallel to RN-4 at Antanimbray village, 17°10'79"S, 46°50'97"E, Betsiboka River drainage, Madagascar, elevation 246 meters".
Pachypanchax varatraza is a species of Aplocheilid killifish endemic to Madagascar where it is found in the Menambery, Fanambana and Ampanobe rivers. Its natural habitat is streams and pools. It is threatened by invasive species.
The katrana is a species of fish in the Bedotiidae family. It is endemic to the basin of Lake Alaotra in Madagascar. Its natural habitats are rivers and freshwater lakes. It is threatened by habitat loss. This species was described by Jacques Pellegrin as Atherina alaotrensis with the type locality of Lake Aloatra.
Aristotle's catfish is a species of fish in the family Siluridae. It is endemic to Greece, where it occurs in the Acheloos River drainage. Its natural habitat is freshwater lakes. It is threatened by habitat loss. This species grows to a length of 46 centimetres (18 in) TL and is of importance to local commercial fisheries. It is known from Lake Trichonida, Lake Lysimachia and Lake Amvrakia and introduced to Lake Volvi and Lake Ioannina in the 1980s thus exclusively lives in lakes. Threats may be water pollution and overfishing.
Osteobrama cotio is a species of ray-finned fish in the genus Osteobrama. This species had three subspecies named O. cotio cotio, O. cotio cunma and O. cotio peninsularis but these are now considered separate species. This species is found in the drainage basins of the Ganges-Brahmaputra including Jiri River in Manipur, Barak River in Silchar, in Brahmaputra River, Uzan Bazaar in Assam, and in Bihar, Madhya Pradesh, Uttar Pradesh, and Punjab in India, and in Bangladesh. The presence of O. cotio in southern India and from the Indus basin of India and Pakistan needs to be confirmed. This species is threatened by extensive loss of habitat caused by pollution and deforestation.
Pachypanchax patriciae is a species of killifish from the family Aplocheilidae. It is endemic to Madagascar where it occurs in the basins of the Mananjeba, Mahavavy du Nord, Ifasy, Manehoko and Ampandra rivers in the north west of the island. The specific name of this fish honours the Malagasy conservationist Patricia Yazgi (1946-2006), who ran the charity Friends of Fishes and who supported efforts to document and conserve the freshwater fish fauna of Madagascar. This species appears to feed mainly the adults and nymphs of terrestrial insects and on the larvae of aquatic insects and its most important predators are fish-eating birds and dragonfly nymphs. It may, however, be threatened by introduced alien fishes in some areas.
