Breeding
Pairs lay eggs on a hard surface next to their anemone and the male guards them until they hatch after about a week. Captive breeding is well established, though rearing the larvae needs rotifers and careful husbandry.
Good to know
This is the most aggressive clownfish and large females will attack tankmates, other clowns and even the keeper's hand, so avoid keeping it with other anemonefish. Captive-bred stock is widely available and preferable to wild-caught fish.
