Marine Fish

Sphyraena barracuda

The Great Barracuda is an extremely large fish with a silvery silhouette.

It is very hardy, long-lived, aggressive, and difficult to house with any other fish smaller than itself. A 150 gallon or larger aquarium is sufficient to start with as a juvenile. As an adult, it will require as much room to swim as possible in a 500 gallon or larger tank; long aquariums or circular raceways are preferred.

The diet of the Great Barracuda consists of smaller feeder fish and chunks of other meaty foods.
