starts withBlue lyretails are sexually dimorphic. The males are more colourful than the females and have wavy lines of red spots which run along its body. The outer margins of the dorsal, anal and caudal fins are tinted with yellow. The females are less brightly coloured and have brown spots rather than red. They grow to a maximum total length of 6.5 centimetres (2.6 in).
The blue lyretail inhabits the tributary streams and marshes of the Benue and Cross River basins of Nigeria and Cameroon.
The blue lyretail occurs in both savanna and forested regions. The males are larger, more colourful and have larger extendable fins than the females. The males are territorial. The waterbodies in which this species occurs are of an unpredictable nature and it has evolved a spawning strategy which is frequently referred to as a "switch" or "semi-annual" breeding strategy. This means that the eggs can survive a period of drying but that they are also viable when permanently submerged. Submerged eggs normally hatch in around 14–21 days depending on the temperature of the water. The eggs are laid on the bottom.
