Dwarf Neon Rainbowfish

The Dwarf Neon Praecox Rainbowfish (Melanotaenia praecox) is one of the most popular and colorful rainbowfish species.  It lives in very large schools in areas with dense vegetation, so it is an ideal candidate for the planted aquarium and appreciates floating plants in its habitat.  As an adult, this rainbowfish's body features iridescent scales in several different shades of blue,  accented with bright red fins.  As with most rainbowfish, mature males display the brightest coloration, particularly while competing/posturing with other males.  Females also possess the same attractive coloration, but to a lesser extent.
