The Ocellaris Clownfish, also known as the False Percula Clownfish, False Clown Anemonefish, and Anemone Demoiselle, is found associating with anemones throughout the Indo-Pacific. It can attain a length of 3.2" (8 cm) in the wild, but aquarium specimens rarely exceed 2" (5 cm) unless they are imported large. This fish is sometimes sold as the Percula Clown, even though it is not. The color pattern is very similar, but it is not as bright orange. The advantage of the Ocellaris is that it is much hardier.

It is a long-lived clownfish that is excellent for the beginner hobbyist. It does best in the presence of anemones such as Heteractis magnifica or Stichodactyla sp. Like the related damselfish, it is well-suited for all but the most predatory tanks.

Tank raised clownfish are very hardy and durable fish making them a perfect addition for the novice or seasoned aquarist. If introduced to the aquarium at the same time, many varieties of tank raised clowns can be maintained together in the aquarium.

Although there are no external characteristics to differentiate male and female, most are born as females and become males as needed. A pair will lay eggs just under the oral disc of the host anemone, using it to protect the eggs. The eggs normally appear olive green in color. Without proper preparation, rearing in the average tank is nearly impossible.

This clownfish is an aggressive eater. It will take most meaty foods and frozen herbivore preparations.
