There are total 28 different species of this fish. They prefer to live in warm water, in close proximity of coral reefs. They are known to inhabit Indian Ocean and Pacific Ocean, Red Sea and Australian Great Barrier Reef. They are not found in the Caribbean Sea, Mediterranean Sea, or Atlantic Ocean.

Clownfish and anemones: –

The clownfish is also known as the anemonefish as it lives in community with sea anemones. They have a symbiotic relationship with anemones which means both of them have benefits from mutual life. These fish gently touch anemones’ tentacles with their different body parts before taking up the residence.

They are immune to the venom of anemone because of a thick layer of mucus on the surface of the body. It also makes them the only fish that do not get stung by the tentacles of the sea anemone.

They cannot survive without having a host anemone because anemones’ tentacles protect them. Although they do not require an anemone in order to survive in an aquarium.
