    Some fish can change their sex all the time

    Bluebanded goby fish, about 2 to 2.5 inches long, are able to change their sex when it suits their position in social hierarchies.
    We can detect within minutes, via changes in behavior, when a fish begins the transition, and it generally takes one to two weeks to complete the transition from female to male, Grober explained.

    For sex change in either direction, there seems to be one guiding social principle: If subordinate, be female. Because each group had only one dominant individual, each group ended up with only a single male.
