Sergeant Major Fish are known for their distinctive black and yellow stripes, which run horizontally along their body, and their vibrant yellow fins. They are a popular species among aquarium hobbyists due to their small size, peaceful nature, and relatively low maintenance care requirements.
Introduction to Sergeant Major Fish
Sergeant Major Fish are a relatively small species, typically growing to a length of 3-5 inches (7-13 cm). They are a schooling species and are often found in large groups in the wild. In captivity, they can be kept in small schools, but it is recommended to keep them in pairs or small groups of 3-5 individuals to prevent aggression and territorial behavior. Sergeant Major Fish are omnivores and feed on a variety of food sources, including small crustaceans, plankton, and algae. In aquariums, they can be fed a diet of high-quality commercial flake food, supplemented with live or frozen foods such as brine shrimp, mysis shrimp, and algae.
