The stoplight parrotfish is a protogynous hermaphrodite that shows full sexual dichromatism, meaning that it changes its sex from female to male during its lifespan, and its color changes with its sex change. [4] The sex change is most likely due to the control of hormones, in particular, 11-ketetestosterone (11-KT). [5] The timing of the sex ...
The males can change sex to female during their lives, and live in a harem in which an established dominance hierarchy manages the group and keeps individuals at a specific social rank. All anemonefish are protandrous hermaphrodites, meaning they first develop into males and may become females later in life.

If the female anemonefish is removed from the group, such as by death, one of the largest and most dominant males becomes a female. [16] The remaining males move up a rank in the hierarchy. Clownfish live in a hierarchy, like hyenas, except smaller and based on size not sex, and order of joining/birth.
Like many wrasses, the hogfish is a sequential hermaphrodite, meaning it changes sex during different life stages; it is a protogynous, "first female" hermaphrodite; juvenile hogfish start out as female and then mature to become male. The change usually occurs around three years of age and about 36 centimetres (14 in) in length. [6]
As in other parrotfish species, males are territorial. They are born female in a female-dominated civilization and can only change their gender as they mature, usually as they get older. This shift is a result of social and environmental factors. When there isn't a male in the group, activation takes place.
Goldfish has just announced that it's embracing its more mature, sophisticated side with a fitting new name. As of today, Goldfish will now be known as Chilean Sea Bass crackers.
The common name of "Amazon molly," acknowledges this trait as a reference to the Amazon warriors, a female-run society in Greek mythology. [4] The Amazon molly is a hybrid species, and its parent species are the sailfin molly ( Poecilia latipinna ) and the Atlantic molly ( Poecilia mexicana ). [ 5 ]
