• Ysoude

Mapubi, which is 35 km to the east of Edéa.
Amiet assigned the code PK 18 to the type material, collected on the Edéa - Yaoundé road ' on the left side '.

A species with a restricted area of distribution. Found in a hilly area south of the Sanaga River 50 kms south of Edea & between the Nyong & Sanaga Rivers of western Cameroon.

Small pools in rainforested areas.
Sympatric species include Fp.amieti, A.loennbergi & E.sexfasciatus.

Deep red/brown on the frontal area of the body. Distinguished by the colouration & patterning of the anal fin.

Scheel originally considered this sp. to be calliurum.but noticed a difference in chromosome arm numbers. Amiet considered the colouration to be distinctly seperate from calliurum & ahli.
This, together with a small distribution area prompted him to describe edeanum.

A fairly easy species to breed.
