Big Mushroom (Shi Lang), Green Island -- False clownfish, Amphiprion ocellaris, in a bulbous sea anemone.
Anemonefishes, aka clownfishes, have developed the ability to live among the stinging tentacles of large sea anemones. About a third of the anemonefishes inhabit a specific host anemone.
Anemonefishes live in small social with a single large dominant female, a smaller sexually active male, and from 2-4 even smaller males and juveniles. With the loss of the female, the largest male will change sex and become the harem's new matriarch.
