True Percula Clownfish (Amphiprion percula) is a species from the Indo-Pacific region. There is quite a bit of variation in markings among individuals. A. percula have three white bars. As adults, the bars are often bordered in black, which varies in width. In some individuals it may extend from margin to margin replacing quite a bit of the orange color. The middle bar normally has a forward projection.
The true perculas have 11 dorsal spines compared to the Ocellaris who usually have have 10 dorsal spines.
The two species do not have overlapping distributions. A. percula are found in Northern Queensland and Melanesia, while A. ocellaris are found in the Andaman sea, the Indo-Malayan Archipelago, Philippines, northwestern Australia, coast of southeast Asia northward to the Ryukyu Islands.
True Perculas at approximately 8 - 9 months of age, which is before adult coloration is complete. Once fish are placed in a reef aquarium with strong lighting, the coloration usually develops more black patterns. Some aquarists believe associations with anemones can influence coloration as well.
False Percula Clownfish- (Amphiprion ocellaris) - Generally, most False Perculas are bright orange with 3 complete white stripes. A black line borders these stripes. A.ocellaris does not have a thick black margin around the white bars like True Perculas usually do.
Both species are easy to keep in aquariums. They prefer the carpet anemones as host species, usually H. magnifica, S. gigantea , S. mertensii or S. haddoni. H. magnifica and S. gigantea are extremely difficult to keep, so S. mertensii or S. haddoni are preferred for aquariums
