Fundulopanchax walkeri was a species which has had several controversies over the years. At one time it was thought the fish was actually Fp. spurelli and another period as Fp. litoriseborus.
This is generally an easy species to breed either over peat moss or bottom mops. Incubation is 6 weeks dry or 3 weeks in water.
