(Synodontis ornatissimus)
Synodontis ornatissimus is a species of upside-down catfish that is endemic to the Democratic Republic of the Congo where it is found in the Ubangi River drainage. It was first described by Jean-Pierre Gosse in 1982. The original specimens were obtained in Poko, in what is now the Democratic Republic of the Congo. The species name ornatissimus means "very ornate or decorated", referring to the coloration of the fish, with many black spots on the body and dorsal fin, and black bands on the tail.
