The Gertrude’s Spotted Blue Eye Rainbowfish, (Pseudomugil gertrudae) is one of the lesser widespread variants of the Blue Eye Rainbowfish and is native to Indonesia, New Guiniea, and Australia. It lives in very large schools in areas with dense vegetation, so it is an ideal candidate for the planted aquarium and especially enjoys the cover of floating plants. Males display iridescent yellow and blue coloration on their bodies and fins, particularly while competing with other males. The second dorsal and anal fins of males become very extended and fan-like with maturity. Females are typically smaller and often possess an attractive orange-yellow hue.
