Fairy Wrasse vs Anthias: common questions
Are the fairy wrasse and anthias related?
No, they belong to different fish families; their shared harem structure and female-to-male sex change are similar solutions to life on the reef rather than signs of close kinship.
Which group is better known for courtship displays, fairy wrasses or anthias?
Fairy wrasses, whose males intensify their already vivid colouring and perform brief flashing displays to attract females.
What happens when the dominant male dies in an anthias group?
The largest, most dominant female transitions into a male to take over the leadership role, ensuring the harem structure continues, a behaviour documented for anthias that the fairy wrasse shares in principle through its own sex change.
