The evidence on the early embryonic and the larval developmental structure from egg to early larval stages of many marine fishes including anemonefishes under captive conditions is still lacking. In recent years, Studies on captive breeding and larval rearing of clownfish get more attention. Remark on the morphometric characteristics throughout the early stages of growth is the greatest reliable and practical indicator of quality or viability of eggs in teleost. The embryonic development and larval hatching time differ by species and environmental conditions. Therefore, it is very important to study the early ontogeny of A. sebae.
