Study of crossbreeding between False Clownfish, Amphiprion ocellaris Cuvier, 1830 and Percula Clownfish, Amphiprion percula (Lacepde, 1802) was conducted in hatchery in Kasetsart University. Six pairs of broodfish were employed in the study. The experiment consisted of two treatments with three replications each. The 1st treatment the male broodfish was a False Clownfish and the female broodfish was a Percula Clownfish, while in the 2nd treatment the male broodfish was a Percula Clownfish and the female broodfish was a False Clownfish. The experiment was carried out for one year. In the 1st treatment only the 1st and 3rd pairs, the broodfish were mated and laid the eggs. The 1st pair laid once and 3rd pair was five times. An average number of eggs were 319 eggs/time. However, only on the second time of 3rd pair, the eggs were hatched out with a hatching rate of 11 percent and the survival rate at the 30 days of nursing was 22.5 percent. The external characteristic of hybrid fish was similar to False Clownfish.
