Gertrude's Spotted Blue Eye Rainbowfish (scientific name: Pseudomugil Gertrudea) is a variant of the blue eye rainbowfish. The males are normally seen in moderately compressed and elongated bodies covered with iridescent yellow and blue coloration, while the females are typically smaller and have an attractive orange-yellow hue. Their fins are the highlight parts of their appearance as they display the special white silvery-grey or yellow with rounded or oblong dark spots scattered all over.

The beautiful Gertrudea’s Spotted Blue Eye Rainbowfish is an outgoing, hardy, and easy-to-care-for species. In wild habitats, they are mostly found in densely floating planted areas with quite low water hardness. Hence, they appreciate home aquariums sharing similar conditions. The species is also known for its inability to cope with various ranges of water parameters; therefore, creating and maintaining a stable living condition is crucial for them to thrive.

Gertrudea’s Spotted Blue Eye Rainbowfish is a shoaling fish. They are normally kept in groups of 8 or more and in no circumstances be kept in single. Otherwise, the fish tends to be frightened and get stressed easily. As a completely peaceful species, Gertrudea’s Spotted Blue Eye Rainbowfish can be housed with other fish as long as they have comparable size, disposition, and living requirements. Be careful when choosing their tank mates since your Gertrudea’s Spotted Blue Eye Rainbowfish are timid and easily out compete for food by more aggressive eaters. Providing a lot of swimming space and hiding places is important if you keep many males in the same tank. It is reported that the dominant males may show harassment behaviors toward the subdominants in certain cases. 

Some experienced aquarists tip that your aquarium may look more attractive if Gertrudea’s Spotted Blue Eye Rainbowfish are kept with dark substrate. In this case, their coloration will be more intense and surely a focal point of the tank.
