In a present day, the most popular program for rehabitation of marine animals is anemonefish releasing program, in some cases the nearly zero of survival rate was reported. Thus this study was established for finding suitable releasing method in order to increase of survival rate. The experimental site was located in the northern island of Mu Koh Ha Yai ,Krabi Province. Based on the results of previous study, mortality rate of released anemonefishes mainly caused by predators. For avoid attacking by wild predators a metal meshed cage was installed over each unoccupied anemones (Heteractis magnifica) for 25 cages, then false clown anemonefishes (Amphiprion ocellaris Cuvier, 1830) was released in ration of 4 fishes per cage. Two hours later, the survival rate was 67 percent and decreasing rapidly to 31 percent after 1 day. One month of releasing period, the survival rate was 10 percent.
