Description

Hylopanchax stictopleuron, the blue lampeye, is a very small killifish from the Central African rainforests. The species reaches only a few centimetres and has a slender body with a bluish sheen, fine spots on the flank and the shining upper eye characteristic of lampeyes. It inhabits small, shaded forest brooks and streams, usually of the black-water type, under dense canopy. It is not a seasonal killifish. The diet consists of small zooplankton and insect larvae at the water surface. Owing to its small size the species has no fishery value and is mainly of interest for the biodiversity of rainforest habitats.
