Ouémé

'Barbus' sublineatus is a widespread West African barb found in river basins from Senegal east to Cameroon, including the Niger and Volta. It is very variable in patterning and can be difficult to identify: Upper Niger fish show three elongate midlateral markings, Middle Niger fish a continuous band and Volta fish four spots. It may prove to be a complex of closely-related species. Little is known of its captive care.

Parachanna africana is an African snakehead found from Benin to Nigeria, in lowland coastal rivers draining into the Gulf of Guinea. Sometimes called the 'Niger snakehead', it is uncommon in the trade, and its name is sometimes misapplied to P. obscura. A series of 8-11 dark chevrons along the body identifies it, though these may not show depending on mood. It is best kept in a species-specific aquarium with a tight-fitting hood.
