Abstract
    Juvenile anemonefish Amphiprion ocellaris were tested in two behavioural laboratory set-ups for their ability to visually or chemically recognize conspecifics. Individuals of two other species of anemonefish, A. clarkii and Dascyllus aruanus, were also used as test specimens for recognition. The results indicate that juvenile A. ocellaris recognize conspecifics visually rather than by olfaction. This is contrary to their finding mechanism of their host anemone. However, the results also indicate that the juvenile A. ocellaris are neither attracted nor deterred by the presence of conspecifics. This is contrary to the settling mechanisms of the damselfish D. aruanus and D. reticulatus, and of the temperate herring Clupea harengus. Hence the results emphasize the variation of sensory abilities and behaviours in fish larvae and juveniles. It is not an area prone for generalizations.
