Orange-face butterflyfish, Chaetondon larvatus, are common in the central Red Sea from Hurghada south. They feed exclusively on table coral (Acropora) where they are seen in pairs from 4 to 12 m.
New research indicates that these butterfly fish grow quickly in their first year, but that growth decreases in their second and third years. When fish get to three years they stop growing and reach their maximum size of 12 cm. There is no difference in the growth of males and females
