Overall preferences, based on initial approach, are for large fish and females, and blue boxes, as opposed to small fish or males and orange or colorless boxes. Male zebrafish preferred females; females had no gender preference. Females and males preferred blue over colorless, while males approached blue and orange boxes equally.
