Amongst the 1,000 different type of anemone species that are in the ocean, only 10 species can have an obligatory symbiosis with the clown fish. They are highly dependent on each other for survival. The mutual symbiotic relationship between these two is reached in many ways. The clown fish lives between the anemones tentacles benefiting from its nutrients and cleaning the anemone. Also giving each other mutual protection from predators, like the butterfly fish.
