• Edoum - Imported to Germany by Roland Numrich on more than one occasion including 1988 where he collected them here. The biotope was a small stream passing through a wood near Edoum where it passes under a road. The stream bed was very muddy, thought to be due to de-forestation upstream where trees were cleared & burnt. In the summer of 1988 the stream width was 2 metres near the road. A.mimbon was the most common killie here but also found were Episemion sp.aff.callipteron & a particularly intensely coloured A.herzogi.

Akoga, which is 55 km from Mékounou, northern Gabon.

The upper Abanga, upper Nkam, upper Mbei & upper Komo River drainages of northwestern Gabon probably extending to southeastern Equatorial Guinea.

The type locality was a small brook draining into the Mvé River.

Small rainforest streams in hilly areas..

Caudal fin has very wide yellow marginal bands top & bottom to the caudal fin.

Reportedly difficult. Eggs are laid in peat fibre/plants/mops & can be safely left with the parents where a few will grow on. Growth is slow with sexual maturity taking 8 months. Young fish are sensitive to waste products in the water. Also, they are sensitive to water changes so small regular water changes are required.

Karl Heinz Notzon put a breeding report in BKA Newsletter No.324 (Sept.1992). He received eggs which needed help in hatching with a little dry food. Fry grew on to 2·5cm in 7 weeks. At this size males started to show. Only one female was found out of 18 fish.
It was felt that regular water changes were essential with this sp. For breeding a water temperature of 18 - 22°C, pH 6 & medium hardness were used. The capacity of the tank was 5 litres. Eggs were laid on mops & peat fibre.Eggs were stored on moist peat.
