Signifer Rainbow

This beautiful rainbowfish is an excellent nano species and it is one of the most variable and versatile species of its family!

The Pacific Blue Eye Signifer Rainbowfish (Pseudomugil signifer) is the most widespread and variable of the blue eye rainbowfish that inhabit the freshwater and brackish rivers and estuaries of coastal Western Australia. It lives in very large schools in areas with dense vegetation, so it is an ideal candidate for the planted aquarium. While some populations of this fish inhabit brackish or even fully marine water, it is not necessary to provide brackish water in the aquarium. Males display brilliant yellow to the orange coloration on their bodies and fins, particularly while competing/posturing with other males. Females also possess this attractive coloration, but to a lesser extent. Both males and females feature stunningly bright blue eyes that contrast beautifully with their yellow to orange bodies.
