Where is the fiercest fish?

It's impossible to say definitively which fish is the "fiercest" as fierceness is a subjective term and can be interpreted in many ways.

However, here are a few fish known for their aggressive nature, powerful jaws, and predatory skills:

* Barracuda: These torpedo-shaped predators are known for their lightning-fast speed and razor-sharp teeth. They can grow up to 6 feet long and have been known to attack humans.

* Great White Shark: While not technically a fish (it's a cartilaginous fish), the Great White is arguably the most feared creature in the ocean. Its size, power, and hunting skills make it a formidable predator.

* Tiger Fish: Found in African rivers, these fish have a reputation for their sharp teeth, powerful jaws, and aggressive behavior. They are known to attack anything that enters their territory, including humans.

* Piranhas: Although they are often depicted as aggressive man-eaters, piranhas are generally scavengers that eat dead fish and insects. However, they can become aggressive if they are threatened or hungry.

* Goliath Tigerfish: This massive fish, native to the Congo River, is known for its sharp teeth and aggressive nature. It's a powerful predator that can grow up to 5 feet long.

Ultimately, the fiercest fish depends on how you define "fierceness." Whether it's based on hunting prowess, aggression, or sheer size, these fish are all worthy contenders for the title.
