Editor's note: Although the term encompasses around 30 species, the clown fish we all know and love is the orange and white Amphiprion ocellaris, the fish who burst into the public consciousness when “Finding Nemo” was released in 2003. One of the “great 8” of Australia’s Great Barrier Reef, clown fish are both an important symbol of ocean conservation and beloved as aquarium pets. Enjoy this gorgeous collection, get some cool Clown Fish wallpapers, and, as Dory famously advised Nemo, “Just keep swimming!”
