The Sergeant Major Damselfish is primarily white with approximately five horizontal stripes and a patch of yellow near the dorsal fin. As the fish matures, it tends to lose color.
It can become aggressive towards other, weaker fish and needs a 50 gallon or larger aquarium with numerous hiding places. It is a very resilient fish.
The diet should include a variety of meaty foods, herbivore preparations, and flaked foods.
