The fish's body is yellow-orange to dark brown. As the name suggests, the two-banded anemonefish has two white bands or bars, with black edges. The head-bar considerably wider. They have 9-10 dorsal spines, 2 anal spines, 15-17 dorsal soft rays and 13-14 anal soft rays. Males grow to a length of 10 centimetres (3.9 in), and females grow to a length of 14 centimetres (5.5 in). In a group of clownfish, there is a strict dominance hierarchy. The largest and most aggressive fish is female and is found at the top. Only two clownfish, a male and a female, in a group reproduce through external fertilization. Clownfish are sequential hermaphrodites, meaning that they develop into males first, and when they mature, they become females. Learn more about Twoband Anemonefish
