Well let me give you the reason, they are known for eating everything from people to fish! Also, their defense can be just biting another fish. They really don't have a predator so most of the time its chomp! But if humans try to catch them...you are in trouble so watch out!
The main and only mean of protection for clown fish is the anemone. This is the reason why clown fish spend all their lives swimming nearby anemone. They protect each other. It is called "symbiosis".

What's generally known as a "stone fish" (though many other fish are often given this name) a bony, saltwater, bottom-dwelling fish with cryptic camouflage that's normally found in Australia and Indonesia. It has spines on its back that, if stepped on, inject the victim with deadly venom as a defense mechanism.
When the puffer fish inflates its body to increase its size it is a behavior called a defense mechanism. Puffer fish have highly elastic stomachs and the ability to quickly take in air or water to puff themselves up. This turns them into an inedible ball.
