The clark's anemonefish is found in outer reef regions and forms a symbiotic relationship with sea anemones for protection from predators. It has an omnivorous diet, consuming small organisms and detritus. The species begins as a male and can change into a female if needed. It practices monogamy and pairs during breeding, with males guarding eggs attached to a surface. The species can live up to eleven years.

Coral reefs are colonies of tiny animals thriving in nutrient-poor marine waters, typically in shallow, productive regions on solid substrates. Composed of calcium carbonate secretions, they serve essential ecological, economic, recreational, and cultural roles. They offer shelter and sustenance to various marine life, protect coastlines from storms and erosion, support fishing and leisure activities, and are part of cultural heritage. Around 10% of Qatar's seabed is covered by coral reefs, vital to over 80% of the Gulf's fish species. Noteworthy Qatar reefs are near Halul Island, Othman Reef, and Khor Al Udaid. Unfortunately, these reefs are endangered, as evidenced by a significant decline in coral health.
