Raiamas senegalensis (silver fish, Senegal trout barb or Senegal minnow) is a species of cyprinid fish in the genus Raiamas from western Africa east to the River Nile. [2] It sometimes is found in the aquarium trade.
Raiamas senegalensis has eleven dorsal soft rays and 16 anal soft rays. It is usually marked with less than 15 vertical bars on its sides and a round spot on caudal peduncle. [2] The background colour is silvery with a greyish green dorsum, the vertical bars decrease in size towards the head. The maximum total length is 245 mm (9.6 in). [4] It is not sexually dimorphic. [4]
Raiamas senegalensis is found in western Africa as far east at the Nile basin. It is found in the basins of the Nile, Lake Chad, Niger, Gambia, Senegal, Volta and the coastal basins of Sassandra, Bandama, Comoé, Tano, Pra, Ouémé, Ogun and Sanaga, which seems to represent its southern distributional limit; it is also known from the Cross River in Cameroon. This means that the countries this species has been recorded in are Benin, Burkina Faso, Cameroon, Central African Republic, Chad, Egypt, Ethiopia, Gambia, Ghana, Guinea, Ivory Coast Mali, Niger, Nigeria, Senegal, Sudan and Togo.

Raiamas senegalensis is a freshwater demersal fish. [1] It is predatory planktophage of non insect plankton during the day but switches to insect plankton at night [5]
Raiamas senegalensis is traded within the aquarium trade. [1]
Raiamas senegalensis has a wide distribution, there are no known major widespread threats so it is therefore listed as Least Concern. [1]
The African palm swift is a small swift. It is very similar to the Asian palm swift, Cypsiurus balasiensis, and was formerly considered to be the same species. The Malagasy palm swift was also recently split from this species. This is a common species with a very wide distribution which faces no obvious threats and may be increasing in numbers as a result of the cultivation of the exotic Washington palm, so the International Union for Conservation of Nature has rated its conservation status as being of "least concern".
The African manatee, also known as the West African manatee, is a species of manatee that inhabits much of the western region of Africa – from Senegal to Angola. It is the only manatee species to be found in the Old World.
Polypterus senegalus, the Senegal bichir, gray bichir or Cuvier's bichir, and sometimes called the "dinosaur eel", "dinosaur bichir", or "dragon fish" is in the pet trade due to its lungfish-like appearance, which was described as more primitive and prehistoric than other modern fishes. It is a prototypical species of fish in the genus Polypterus, meaning most of its features are held across the genus. It is commonly kept in captivity by hobbyists. They are native from Africa where they are the most widespread species of the genus.
The African arowana or Nile arowana is a species of bonytongue. Despite being called an "arowana", the African arowana is more closely related to arapaimas, the only other members in the subfamily Arapaiminae, than the South American, Asian, and Australian arowanas in the subfamily Osteoglossinae. Compared to these, the African arowana has a more terminal mouth and is the only one that feeds extensively on plankton.
The freshwater butterflyfish or African butterflyfish, Pantodon buchholzi, is the only extant species in the family Pantodontidae within the order Osteoglossiformes. It is not closely related to saltwater butterflyfishes.

Furthermore, it is also known from East Africa and the middle reaches of the Congo. Records from the Zambezi drainage need confirmation.
