These babies were hatched in the tank after the Great Barrier Reef tank was renovated, with the eggs laid by the parent fish being collected by the aquarium keeper. Although still small, they have grown to the point where their distinctive features, such as their yellow heads and the black stripe running from their eyes to their dorsal fins, are clearly visible. You can also watch aquarium keeper explain the species and feed them daily from 1:10 PM to around 2:00 PM. Information about the breeding behavior of Barrier reef chromis and other damselfish species is also available on the blog "Behind the Scenes at Kaiyukan ."
