“…Studies have shown a correlation between brightness of belly colour and timing of egg development and spawning, making belly colour an effective signal of readiness to spawn (Amundsen & Forsgren, ; Baldauf et al ., ; LaPlante, ; Svensson et al ., ). For example, belly colour displayed by female Halichoeres margaritaceus intensified from white to pink to red, peaking in redness just before spawning (LaPlante, , ). Evidence exists that the area of pink belly colour displayed by female M. ramirezi varies across individuals (unpubl.…”

Male ram cichlid, Mikrogeophagus ramirezi, spent significantly more time associating with animated female images compared to static images of the same female, indicating that males of the species reliably respond to computer‐animated images of conspecific females. Female M. ramirezi temporarily display a pink‐coloured belly, and this study showed that males spent significantly more time associating with animated female images displaying a pink‐coloured belly compared to animated female images with pink belly colour removed. This is the first study to report male mate choice in M. ramirezi, a neotropical monogamous dwarf cichlid.

“…Carotenoid colouration (yellow, orange and red) is used in the marine environment to advertise quality (Svensson & Wong, 2011 ). For example, female two‐spot gobies ( Gobiusculus flavescens ) develop bright orange bellies in the breeding season to attract male mates (Svensson et al, 2006 ), and the aptly named pink‐belly wrasse ( Halichoeres margaritaceus ) advertises its readiness to spawn by shifting its usual abdomen colour to red (LaPlante, 2015 , 2017 ). However, sexual signalling in the marine environment can also involve purely achromatic signals.…”

Dynamic colour change as a signalling tool in bluelined goatfish (Upeneicthtys lineatus)

Many animal species can rapidly change their body colouration and patterning, but often the ecological drivers of such changes are unknown. Here, we explored dynamic colour change in the bluelined goatfish, Upeneichthys lineatus, a temperate marine teleost species. Upeneichthus lineatus can change in a matter of seconds, from a uniform white colour to display prominent, vertical, dark red stripes. Initial observations suggested that rapid colour change in U. lineatus was associated with feeding and may act as a signal to both conspecifics and heterospecifics that are frequently observed to follow feeding goatfish. Field observations of the colour and behaviour of individual U. lineatus were collected to (1) document the repertoire of behaviours that U. lineatus displays and categorise associated colour patterns; (2) quantify the speed of dynamic colour change; (3) establish the context in which U. lineatus changes colour and pattern; and (4) test whether the behaviour of follower fishes is influenced by colour patterning or specific behaviours of the focal goatfish. We found that U. lineatus changed colouration from white to the red banded pattern in less than 10 s. The key driver of rapid colour change in U. lineatus was feeding, particularly when the fish fed with its head buried in sediment. Conspecific followers were most likely to be white in colour and adopt searching behaviour, regardless of the focal fish colour or behaviour. Other species of follower fish spent significantly more time following U. lineatus that were displaying dark red stripes when searching or eating, implying the red stripes may be an interspecific signalling mechanism. Our findings indicate that rapid colour change in teleost fish may be used for social communication and may provide U. lineatus with increased protection from predation when feeding via a safety‐in‐numbers approach.
