Kienké

Barboides gracilis is a miniature cyprinid from coastal West and Central Africa, ranging from Benin through Nigeria and Cameroon to Equatorial Guinea. Adults measure less than 20 mm SL, and it inhabits slow-moving, shady rainforest streams and swamps with dense marginal vegetation. It has a following among enthusiasts of planted 'nano' aquaria and may be sold as 'dwarf amber/ember barb'. Very peaceful but timid, it is best kept alone or with other diminutive West African species.

The six-barred panchax, Epiplatys sexfasciatus, is a killifish from coastal regions between Gabon and Ghana. Well established in the hobby in several forms, it has a confusing taxonomy, and some authors restrict it to northwestern Gabon and Equatorial Guinea and treat other populations as subspecies. It mostly inhabits freshwater swamps and minor tributary streams, and is relatively easy to breed.

Lönnberg's lyretail, Aphyosemion loennbergii, is a killifish from southwestern Cameroon, described from the Kienké river (formerly the 'Kribi'). It has a wider distribution in the region and also occurs in the Lokundje and Nyong drainages.
