Common name: Damselfish

Stegastes is a genus of fish in the family Pomacentridae, commonly known as damselfish or sergeant majors. These small to medium-sized fish are known for their vibrant colors and territorial behavior. They are popular in the reefkeeping hobby due to their hardiness and adaptability to aquarium life. Stegastes species often establish territories around coral heads or rock formations and can be quite aggressive in defending their space. They are omnivorous, feeding on algae, small invertebrates, and plankton. While they are generally easy to care for, their aggressive nature should be considered when adding them to a community tank.
