All clownfish born as males

[IlianaM]

I have read that all clown fish are born males--but I have also read that all clown fish are born as "genderless" non-sexual juveniles, and that in a group, only the breeding pair contains a true male. What is accurate?

[J.B.]

Clownfish are born as males and when two or more are housed together, the dominant male will morph into a female and grow larger than the male fish.
