The Tomato clownfish is named for its bright red coloration, which can vary in shade from burnt orange to tomato red. They are one of the larger clownfish species, and can be one of the most aggressive. Females are generally larger than the males, and clownfish have the ability to change sex from male to female. In the Fiji exhibit, Tomato clowns frequently lay eggs, usually on the underside of a rock, and just underneath the safety of a large anemone.
