Orange clownfish

Amphiprion percula can grow to be 11 cm (4.3 in) in length, but is on average 8 cm (3.1 in), and can be recognized by three white lines across their bright orange bodies, with no distinction in color between sexes. The anterior white bar is placed just behind the eye, the middle bar goes straight down the middle of the fish, and the posterior bar occurs near the caudal fin. An anterior projecting bulge also exists on the middle bar. In addition to the white coloring, black edging outlines each fin with varying thickness. This species can be mistaken for the similar species of clownfishes, A. ocellaris. This is known as the ocellaris clownfish and sometimes referred to as the "false percula clownfish" or "common clownfish" due to its similar color and pattern. The "easiest" way to distinguish the two species is the fact that A. percula has 10 spines in the first dorsal fin and A. ocellaris has 11, which is a more reliable distinction than color patterns. A. ocellaris does not have thick black edging outlining the fins.
