Sergeant Majors

What they look like – silver fish with a yellow band on top and five vertical black bars, resembling the insignia

of a sergeant rank in military services. Usually around six inches in length and are found all over the Caribbean.

What they eat – A non-picky eater, sergeant majors will feed on algae, plankton, other fish and anything they find floating in the ocean.

Adults will often form large feeding aggregations which can contain hundreds individuals and when they swarm you while snorkeling there is nothing else like it!

Color and Personality Change!

Male sergeant majors will create nests on hard substrates where females will lay their egg masses.

The males then turn a dark blue color and defend their nests violently, making them pound for pound one of the most vicious fish on the reef.
