How to tell if they are male or female?

The dorsal and anal fins of the males are transparent with narrow yellow margins. The pelvic and pectoral fins are often tinged with red. The caudal fin lobes are yellowish with black dorsal and ventral margins. Females caudal fin lobes are yellowish while the pectoral and pelvic fins are transparent. The outer part of the second dorsal fin is yellowish. The body scales have a slight dark edge. They differ from most other forms of Pseudomugil from Australia and New Guinea, in having the caudal fin longer and more deeply forked. Males are easily distinguished from females by their brighter colours and longer and more elongated dorsal fin.
