[Limited Time Only] Baby Barrier reef chromis on Display
Baby Barrier reef chromis, a species of damselfish endemic to the Great Barrier Reef, the world's largest coral reef, are on display for a limited time at the aquarium keeper counter on the 4th floor of the entrance building. 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 ." Period: February 20, 2026 - April 20, 2026 (tentative) Location: aquarium keeper Counter, 4th Floor, Kaiyukan Entrance Building *The exhibition may be suddenly canceled depending on the condition of the animals. Barrier reef chromis ( English name: Barrier reef chromis, scientific name: Chromis nitida) is a species endemic to the Great Barrier Reef. Among damselfish, which are generally territorial and aggressive, it has a relatively gentle temperament.
