This is another percula clown fish. Clown fish are probably the only clowns I'm not nervous to be around.
Not many people realize this, but percula clown fish can be very territorial. They are a species of damsel fish, which as a whole are a very aggressive family. If someone wants to have a clown fish in their aquarium, I'd recommend an ocellaris clownfish. They are practically identical to perculas, but they are hardier and less aggressive. The club I run happens to have an ocellaris, and he's well over a year old and still doing the "happy clown fish dance".
