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. [citation needed]
In fish, reproductive histories often include the sex-change from female to male where there is a strong connection between growth, the sex of an individual, and the mating system within which it operates. [55] In protogynous mating systems where males dominate mating with many females, size plays a significant role in male reproductive success ...
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.
The males do not have to compete with other males, and female anemone fish are typically larger. When a female dies a juvenile (male) anemone fish moves in, and "the resident male then turns into a female and reproductive advantages of the large female–small male combination continue". [22] In other fishes sex changes are reversible. For ...

It is a carnivorous fish which mainly feeds on molluscs and crustaceans. The blue-throated wrasse is a protogynous hermaphrodite, females change sex into males, which happens after they attain 4 years of age, [3] and this occurs in 12% of females each year. [1] This oviparous species spawns in the Spring [3] and form pairs to do so. [2]
