History

Scheel in ROTOW 1 mentions this fish although at the time they were thought to be A.louessense. He gives 2 colour photos on pages 276 & 277. In 1964 live fish were collected by Brichard & Roberts. The Danish United Nations Military Forces which were serving in the Congo at this time obtained some specimens which were given to Scheel. Amongst these specimens were an Aphyosemion species which were collected close to Mindouli 'on the upper reaches of the Niari River, an affluent of the Kouilou River'.

Scheel also reported a similar fish kept by Ted Seymour (BKA) in Scotland in 1964.

Lambert also had similar fish from other parts of the Kouilou River drainage. He also had other fish from this drainage which Scheel considered not to be louessense but having 'some traits in common' with his louessense strain.
