Tenellus Blue Eyed Rainbow (Pseudomugil tenellus)


A colorful and active member of the genus Pseudomugil, commonly referred to as “blue eye rainbows” in the hobby, the Tenellus Rainbowfish originates from coastal regions of Northeastern Australia and parts of New Guinea. In the wild, they tend to be found in warm, slow-moving waters and like many close relatives in its genus moves between pure fresh, brackish, and even full-strength marine waters occasionally. Tank raised specimens remain quite salt tolerant but are raised in pure freshwater and do not require additional salt to thrive. In the aquarium, they are best kept in groups and will do well in a well planted tank with plenty of cover and will get along well with most similarly sized peaceful tankmates.
