The blackspot tuskfish (Choerodon schoenleinii) is a big yellow-bellied fish found mostly in the Western Pacific Ocean, swimming in the coral reefs between the Ryuku Islands of Japan, Hong Kong, and Northern Australia. These fishes are locally known by names like green wrasse or bluebone.
In some parts of New South Wales and Indonesia, this species occurs quite frequently. They get their name because of the peculiar black spot that exists behind the dorsal fin of this species of fish.
These fishes have a large body compared to many other coral fishes. Juveniles prefer living in sandy areas of the Pacific coral reef.
These fishes are somewhat sexually dimorphic and the males are predominantly yellow and blue in color while the females have a green color on their body and are yellow-bellied. These fishes belong to the family of Labridae and the genus Choerodon.
