All anemonefish are protandrous hermaphrodites, meaning they first develop into males and may become females later in life.
Some species show functional gonochorism, meaning that they are born functionally either male or female, and remain so for their entire life; there is no sex change. Meanwhile, functionally hermaphoditic species exhibit sex change, and are protogynous , meaning that individuals that are functionally female can become functionally male.
