Percula Clownfish

The Percula Clownfish (Amphiprion percula), also called the Orange Clownfish, is a small anemonefish in the family Pomacentridae, native to the western Pacific around Papua New Guinea, the Great Barrier Reef, and the Solomon Islands. It is one of the most widely recognized reef fish in the world, famous for its vivid orange body and three white bars, and for its close symbiotic relationship with host sea anemones, whose stinging tentacles it is uniquely immune to. This partnership provides the clownfish protection from predators while the anemone benefits from the fish's cleaning and nutrient contributions. The species lives in small social groups centered on a single host anemone and has become a globally familiar symbol of coral reef biodiversity.

The Percula Clownfish is identified by its bright coloration and characteristic banding pattern.

• Vivid orange body, sometimes appearing more red-orange depending on the population
• Three broad white bars, each outlined with a thin black border, crossing the head, midbody, and tail base
• Rounded pectoral and tail fins
• Black edging along the fin margins
• Grows to about 7-11 cm, with females larger than males It closely resembles the False Percula Clownfish (Amphiprion ocellaris), but can be distinguished by having fewer dorsal fin spines (typically 10 versus 11), thicker black bar outlines, and a slightly stockier body shape.

Percula Clownfish inhabit shallow coral reefs and lagoons of the western Pacific, primarily around Papua New Guinea, northern Australia's Great Barrier Reef, and the Solomon and Vanuatu island chains. They live in close association with a small number of host sea anemone species, particularly the Magnificent Sea Anemone and Giant Carpet Anemone, rarely straying more than a short distance from their host. This restricts them to shallow, clear reef waters typically less than 15 meters deep, where suitable anemone hosts are found among coral and reef flat habitats.

Percula Clownfish live in small hierarchical social groups within a single host anemone, typically consisting of a dominant breeding female, a smaller breeding male, and several non-breeding juveniles. All individuals are born male, with the largest fish in the group transitioning to female if the breeding female is lost, a process known as sequential hermaphroditism. They rarely venture far from their host anemone, gaining protection from a mucus coating that prevents them from being stung. Spawning occurs near the anemone's base, with the male guarding and fanning the eggs until hatching. The species feeds on plankton, algae, and small invertebrates gathered near its home anemone.
