The genera Amphiprion and Premnas belonging to the family Pomacentridae and sub family Amphiprioninae commonly known as “clown fishes or sea anemone fishes” are long ranked as one of the most popular attractions all over the world. They were the first reef fish species bred successfully in captivity. However, large scale culturing of clownfish has not always been successful technically due to the lower larval survival which usually go through one or many larval stages, start out at a very small size, and are extremely sensitive to external factors.
