I'm doing the kelp fish.

This fish is a brown fish and lives to be about 20 years old at the most. It stays at about 15 to 80 feet below the surface of the water. and the females and males grow at about the same size and rate except the females grow a little faster. They get to about 17 inches long.

The kelp forest is seen in colder nutrient rich waters and range from both poles.
