The **Sergeant Major** is a vibrant and frequently encountered fish species. These fish feature a predominantly white body adorned with bold black vertical stripes and a splash of yellow on their dorsal side.

**Sergeant Majors** can grow up to 9 inches in length and require a minimum tank size of 125 gallons. Although they are aggressive, they generally coexist peacefully with most fish, corals, and invertebrates, making them an excellent choice for reef aquariums.

In smaller tanks, **Sergeant Majors** may display aggression towards other damselfish and similarly sized species. However, in larger aquariums, schools of these fish can create a captivating display of color and movement. They are known for their outgoing nature and are often visible throughout the day.
