Pseudomugil gertrudae is a Pseudomugilidae from 大洋洲. Its iridescence is honest signalling: colour and condition track water quality and age together. It swims in mid-water. Adults reach 4–8 cm. Shoaling; 8+ in a long tank unlocks full colour. Provide swimming length, clean hard water and a big school; patience does the rest. Maintain 20–26 °C at pH 6.5–7.5. Best suited to a keeper who can match its natural water.
