The study represented an attempt to clarify whether goldfish, after rearing in monochromatic light, show deviations from normal in their colour discrimination ability. Goldfish were made to spawn, the spawn then being distributed to three rearing basins which were illuminated with red (687 nm), blue (434 nm), or white, light. After 14-19 months, fish of all groups were tested for their colour discrimination ability by means of blue-green and red-green discrimination training. No significant differences between the rearing groups were found. Further, for fish of all rearing groups, blue-green discrimination was significantly more difficult than red-green discrimination. Spontaneous colour preferences were not observed. Neither did lightmicroscopic investigation of the retinae reveal differences — the shape and pattern of distribution of the discernible cone types were the same in all groups and corresponded to the descriptions given by other authors.
