Lake Kutubu Rainbowfish

Melanotaenia lacustris

Family: Melanotaeniidae

Ask Finn

The Lake Kutubu rainbowfish is one of the most intensely coloured species in the genus. Males develop a vivid turquoise-blue upper body that grades to silver-yellow on the lower flanks. It is a robust, active fish suited to larger planted or Dutch-style aquariums. The intense colouration only develops fully in mature males in well-maintained water.
