Ctenochromis pectoralis, the Pangani haplo (short for "haplochromine"), is a species of fish in the family Cichlidae. It was originally characterized in the Pangani River of Tanzania, and may also be present in Kenya. It is listed as extinct by IUCN as a result of a 1996 evaluation,[3] but this appears to be incorrect.[2] A more recent IUCN publication stated that this species is not endangered in any way.[4]
Two isolated populations of similar fish have been reported from springs flanking Mount Kilimanjaro, with some disagreement as to whether they represent the same or distinct related species: at the Kikuletwa Hot Springs of Hai District of Kilimanjaro Region, upstream of the Pangani,[5][6][7] and the Mzima Springs, in the Tsavo River drainage, Kenya.[8] The latter is listed as a distinct, vulnerable species, C. aff. pectoralis, by IUCN.[9]

Lake Victoria is one of the African Great Lakes. With a surface area of approximately 59,947 km2 (23,146 sq mi), Lake Victoria is Africa's largest lake by area, the world's largest tropical lake, and the world's second-largest fresh water lake by surface area after Lake Superior in North America. In terms of volume, Lake Victoria is the world's ninth-largest continental lake, containing about 2,424 km3 (1.965×109 acre⋅ft) of water. Lake Victoria occupies a shallow depression in Africa. The lake has an average depth of 40 m (130 ft) and a maximum depth of 80–81 m (262–266 ft). Its catchment area covers 169,858 km2 (65,583 sq mi). The lake has a shoreline of 7,142 km (4,438 mi) when digitized at the 1:25,000 level, with islands constituting 3.7% of this length.
Ctenochromis is a genus of haplochromine cichlids endemic to the Lake Tanganyika and Congo River basins in Africa.
The Pangani barb is a species of cyprinid fish.
The four-spotted barb is a species of ray-finned fish in the family Cyprinidae.
Barbus sp. 'Pangani' is an undescribed but distinct freshwater fish species in the family Cyprinidae. Apparently a close relative of the East African red-finned barb, it is currently under study for its formal description. Until then, this small African barb is provisionally assigned to the genus Barbus, but probably belongs – like "B." apleurogramma – in another genus.
The red Pangani barb is a species of cyprinid fish.
Alcolapia alcalica, the common Natron tilapia or soda cichlid, is an endangered species of fish in the family Cichlidae. It is endemic to the hypersaline, warm Lake Natron in Ngorongoro District of Arusha Region, its drainage and the Shombole Swamps in Kenya and Tanzania. This species typically has an essentially terminal (straight) mouth, but a morph with an upturned mouth is found locally in eastern Lake Natron, where it co-occurs with the normal morph. A. latilabris and A. ndalalani, the two other species in Lake Natron, both have a clearly downturned mouth. Territorial males of A. alcalica have extensive blue-white spotting, and their underparts and throat can be yellow or white. Females and non-territorial males are overall sandy in colour. A. alcalica reaches up to 11.6 cm (4.6 in) in total length.
The Pangani suckermouth is a species of upside-down catfish native to Kenya and Tanzania. This species grows to a length of 7 centimetres (2.8 in) SL.
Trematochromis benthicola is a ray-finned fish species in the cichlid family (Cichlidae), subfamily Pseudocrenilabrinae and the tribe Haplochromini. It is found throughout Lake Tanganyika in the Burundian, the Democratic Republic of the Congo, Tanzanian, and Zambian shoreline. Its preferred habitat are the hidden recesses of caves in shallow water.
Ctenochromis horei is a species of haplochromine cichlid which is found in East Africa.
The Katavi mouthbrooder is a species of cichlid fish endemic to Tanzania where it is found in the Lake Rukwa drainage. This species can reach a length of 9.9 centimetres (3.9 in) TL.
Oreochromis esculentus, the Singida tilapia or Graham's tilapia, is a species of cichlid endemic to the Lake Victoria basin, including some of its satellite lakes such as Kyoga, in Tanzania, Uganda, and Kenya. Its common name refers to Lake Singida, but this population is the result of an introduction that happened in the 1950s. This fish is highly valued by local fishermen, who know it as ngege.
The Lake Chala tilapia is a species of cichlid fish that is endemic to Lake Chala, a small crater lake on the border of Kenya and Rombo District of Kilimanjaro Region in Tanzania. It mostly lives in relatively deep water, at depths between 20–45 m (66–148 ft). It is considered critically endangered by the IUCN, with the two primary threats being deterioration of its habitat due to siltation, and other non-native tilapia species that have been introduced to Lake Chala. Before these introductions, the Lake Chala tilapia was the only fish in Lake Chala. It is very closely related to the similar Jipe tilapia, another highly threatened species from the same general region of Kenya and Tanzania. The Lake Chala tilapia can reach a standard length of up to 30 cm (12 in).
Oreochromis jipe, the Jipe tilapia, is a critically endangered species of cichlid fish native to Kenya and Tanzania, where it is restricted to Lake Jipe and the Pangani River. The population in the Pangani River shows some morphological differences compared to the population in Lake Jipe, and it is sometimes recognized as a separate species, the Pangani tilapia. Whether regarded as one or two species, the Jipe–Pangani tilapia forms a species flock with the threatened Lake Chala tilapia from the same general region of Kenya and Tanzania.
Oreochromis korogwe is a species of cichlid native to Kenya and Tanzania, where it occurs in the Pangani River system, as well as the Zigi River. This species can reach a standard length of 20.8 cm (8.2 in).
Orthochromis kasuluensis is a species of cichlid endemic to Tanzania where it is only known from the upper Ruchugi River drainage. This species can reach a length of 7.8 centimetres (3.1 in) SL.
Orthochromis uvinzae is a species of cichlid endemic to Tanzania where it is only known from its type locality at Uvinza in the middle Malagarasi River drainage. This species can reach a length of 8.6 centimetres (3.4 in) SL.
The Pangani robber is a species of fish in the family Alestidae. It is found in the Pangani River drainages, including Lake Jipe, in Tanzania and Kenya. Its natural habitats are rivers and lagoons.
Synodontis punctulatus is a species of upside-down catfish native to Ethiopia, Somalia and Tanzania where it is found in the Pangani and Shebelle Rivers. This species grows to a length of 25 centimetres (9.8 in) TL.
Astatotilapia bloyeti is a species of haplochromine cichlid from the coastal river systems of Tanzania. Reports from other areas of Africa are considered to refer to related species. The IUCN considers it to be endemic to the Pangani River and includes Kenya in its range. This species taxonomic status is uncertain and some authorities place it in the genus Haplochromis while others retain it in Astatotilapia. This taxonomic uncertainty has led the IUCN to classify this species conservation status as Data Deficient. The specific name honours the collector of the type, Capitaine A. Bloyet, chief of the French research station at "Kandôa, Tanzania".
