Blue Eye Gertrudae ARU II Rainbowfish
The classic blue-eye gertrudae is a beautiful small schooling rainbowfish suitable for planted aquariums and most community fish tanks. As with most rainbow fish, the male gertrudae have larger fins and more color than the female, but boths sexes are attractive. We ship these as close as possible 50:50 mix males and females. We recommend a school of six or more but a pair would do well in a peaceful community tank. The ARU II is a variation bred for higher color (and a little higher price).
