Dwarf Neon Rainbowfish
Melanotaenia praecox
Family: Melanotaeniidae
The dwarf neon rainbowfish is one of the most popular rainbowfish in the hobby, combining a brilliant electric blue body with vivid red fins in males. At just 5–6 cm it is considerably smaller than most melanotaenia and suits medium-sized planted tanks. A large school in a well-planted aquarium under good lighting is a spectacular sight.
