This fish is called clownfish, a tropical saltwater fish, and is one of the common fish on coral reefs.

Clownfish usually have a bright, orange, or yellow body with white or black stripes or spots, very beautiful.

The body of clownfish is small, usually around 10-15cm, mainly feeding on plankton, and small invertebrates, and like to live around corals, anemones, and other solidifying organisms.

Clownfish are relatively active and often weave and swim on coral reefs. They have two dorsal fins and a caudal fin, can swim freely in the water, and can also adjust their posture and speed by fin movements.

Clownfish are dioecious and hermaphroditic creatures and generally choose to live in colonies of corals or anemones, living and breeding with conspecific mates.

Clownfish are very important for their survival status on coral reefs. They serve as a link in the food chain on coral reefs, providing food for other marine organisms.

At the same time, they can eat some of the harmful organisms on the reef, maintaining a healthy ecology of the reef. Because of their bright colours and lovely forms, clownfish have also become one of the representatives of ornamental fish.

In conclusion, clownfish is a very beautiful and interesting marine creature that lives on coral reefs and is an integral part of the marine ecosystem.
