Amphiprion bicinctus

The twoband anemonefish-Kétcsíkos bohóchal The twoband anemonefish, Amphiprion bicinctus (Rüppell, 1830), often called a clownfish or threebanded anemonefish, is the most common clownfish in the Red Sea. This species is well known for its relationship with anemones, a classic example of symbiosis. The tentacles of the anemone protect the clownfish from predators. When the clownfish first contacts the anemone, it jerks back from the stinging nematocysts, but gradually its mucus coating gives it immunity. The anemone benefits by the clownfishes movement among its tentacles, which increases water flow and therefore oxygen. The anemone may also feed on the fish's waste material. Some clownfish live in anemones as juveniles and move to corals as adults. Some never move from their anemones. Some are territorial and will dart meters out and "attack" depth gauges, mouthpieces or divers themselves.
