This study investigated whether male body colour is a trait upon which females of Skiffia multipunctata, a viviparous fish of the subfamily Goodeinae, base their choice of potential mate. About 60% of the males in the study had black patches on the sides of their bodies and/or dorsal fins. Patches varied in number, size and distribution. Most males (70% of the fish in the study) had diffuse orange colouration on their flanks, mainly on the peduncle. The hypothesis was that, after controlling for differences in body size, females would choose males with more black or orange colouration than males with less exaggerated patches of colour. However, in contrast to this hypothesis, females preferentially approached the males with less black colouration. Since orange colouration did not have a significant effect on female response, and there was no correlation between black and orange colours on the males in the study, females rejected males with more black colouration rather than preferring males with more orange or other visible colours. These findings indicate that sexual selection by female mate choice is not driving black or orange male body colouration in Skiffia multipunctata.
