The redspot barb (Enteromius kerstenii) is a species of freshwater cyprinid fish found in East Africa. It is named for the large, orange-red spot found on each operculum.[1]
According to FishBase, the South African Enteromius tangandensis (also referred to as "redsport barb") is a synonym of E. kerstenii, whereas the Catalog of Fishes lists them as separate species.
This species reaches a length of 9cm (04inches).
The fish is named in honor of Otto Kersten (1839-1900), an early explorer of Mount Kilimanjaro, who sent a small collection of fishes to Peters, including the type specimen of this species.[2]
