科: Pseudomugilidae
格氏假鲻银汉鱼为似虹银汉鱼科鱼类，和平但活跃，需要开阔泳动空间，原生分布于大洋洲。虹彩是诚实的状态信号：体色与状态随水质与年龄一起变化。成体约 4–8 cm，群游性，8 尾以上长缸最佳，适宜水温 20–26 °C。缸要长，群要大，水要清。
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.
