Adaptations
A specialized mucus layer and acclimation behavior allow contact with host tentacles that sting many other fish. The anemone provides shelter, while the fish can deliver nutrients, remove debris, circulate water, and defend the host from some predators.
Behavior and daily life
A host anemone supports a size-based group with one breeding female, one breeding male, and smaller non-breeders. Eggs are attached to a hard surface close to the host, and the male fans and cleans them until hatching.
Conservation

The focal species remains widespread, but reef degradation, warming, bleaching, pollution, and collection can affect local fish and host anemones. Other clownfish species have different ranges and should not inherit this status automatically.
Within a clownfish social group, the largest fish is female; if she disappears, the breeding male can change sex and become the new female.
