The slender grouper is the only species in its specific group, called the Anyperodon genus. You can find this fish in the Indo-Pacific region, which covers parts of the Indian and Pacific Oceans.

About the Slender Grouper
What Does It Look Like?
The slender grouper is a medium-sized fish. It can grow to be about 65 centimeters (about 25 inches) long. Its head makes up a large part of its body. The mouth is big, and its lower jaw sticks out further than the upper one.
A special feature of this fish is that it doesn't have certain teeth called palatine teeth. This helps scientists tell it apart from other groupers.
The fish's main color is a light reddish-brown. It has many orange spots all over its body, especially on its head. It also has five light, silvery-blue lines running along its sides. The bottom three lines reach its tail. The top two lines break up into wavy streaks.
Fins and Young Fish
The slender grouper has two main fins on its back. The first one has 11 sharp spines. The second one has 14 to 16 soft rays. Its anal fin, located on its underside, has 3 spines and 8 or 9 soft rays.
Young slender groupers look different from adults. They have bright blue and red stripes along their bodies.
Where Do Slender Groupers Live?
Slender groupers live in a wide area of the tropical Indian and Pacific Oceans. You can find them from the east coast of Africa and the Red Sea all the way to southern Japan and Australia.
They prefer to live around coral reefs and the slopes of reefs that face the open ocean. They also live in calm water areas called lagoons. They usually live at depths of up to 50 meters (about 164 feet). Sometimes, they can be found as deep as 80 meters (about 262 feet). They are also found in the Andaman Sea.
What Do Slender Groupers Eat?
The slender grouper is a carnivore, meaning it eats other animals. It mainly eats other fish, like goatfish. It might also eat small invertebrates, which are animals without backbones.
Clever Mimics
Young slender groupers are very clever. They use a trick called aggressive mimicry. They look and act like two other types of fish: the red-lined wrasse (Halichoeres biocellatus) and the silty wrasse (Halichoeres purpurescens).
By looking like these harmless wrasses, the young grouper can trick other fish. The prey fish think the grouper is just another wrasse and don't see it as a danger. This allows the grouper to get close enough to catch its meal without being noticed.
Is the Slender Grouper Endangered?
The slender grouper is currently considered a species of "least concern" by the IUCN Red List of Threatened Species. This means that scientists are not worried about it becoming endangered soon.
This is because the fish lives in a very large area. Also, the number of slender groupers in the wild does not seem to be decreasing. People do not usually fish for them to sell in large amounts. However, you might sometimes see them in fish markets, like those in Hong Kong.
How People Use Them
- Fishing: They are sometimes caught for small local trade.
- Sport: Anglers (people who fish for sport) sometimes catch them.
