Sergeant Major- Abudefduf saxatilis

Habitat Reef associated

Range Strictly an Atlantic species in many regions such as south coast of the United States, Central America, eastern South America, and western Africa.

Description Large colorful damselfish with five vertical black bars that narrow toward the belly. Adult male is dark blue with the black bars less visible on the body.

Ecological Notes Popular aquarium fish but becomes territorial with age which could create a problem if not closely watched. Should not be kept with others of the same species.

Personal Information When we went to the North Carolina Aquariums I spotted this damselfish swimming around as if to want attention from the people around the tank. Once more people settled in front of the tank with the damselfish it began to swim around more often than it was before anyone was around!
