Percula Clownfish Identification Guide

Key identification features

• Bright orange body crossed by three white bars edged in noticeably thick black borders
• Thick black outlining along the edges of the dorsal, anal, and tail fins
• Ten dorsal fin spines, one fewer than its close relative
• Rounded, compact body shape typical of anemonefish
• Small size, usually under 8 cm
• Middle white bar is wide and often bulges slightly toward the tail

Common look-alikes

• Ocellaris Clownfish: has thinner black outlining on the white bars and eleven dorsal spines instead of ten
• Tomato Clownfish: shows only a single white bar behind the eye rather than three full bars
• Pink Skunk Clownfish: lacks the vertical white bars entirely, showing instead a single white stripe running along the back

Where you'll see one

Percula Clownfish live among the stinging tentacles of specific host anemones on coral reefs of the western Pacific, particularly around Papua New Guinea, the Great Barrier Reef, and nearby island waters, rarely straying more than a body length or two from their host.
