Abstract:A number of studies have been conducted to identify whether fish have preferences for different tank background colors, and it is still in controversy that whether fish is able to distinguish colors and response correspondingly to different colors. In this study, we recorded the time that individual goldfish Carassius auratus spent in white-background and color-background (include red-, orange-, yellow-, green-, cyan-, blue-, purple-backgrounds separately) tanks to test the prediction that C. auratus had preferences for different background colors. The results showed that the differences in time-spent by C. auratus between color-backgrounds and white-backgrounds, as well as among the color-backgrounds were not significant. These results suggested that C. auratus might not be able to distinguish different colors accurately and had no preference for background color. This result that C. auratus was colorblind might be a useful guideline for color design of fish tanks in C. auratus feeding.
