Blue King Tetra

The Blue King Tetra (*Pseudotetra sp.*) is a striking freshwater fish, reaching 2-3 inches (5-7.5 cm) in length, with a vivid blue body and metallic sheen. It is peaceful, social, and thrives in schools of at least six in well-planted tanks with slightly acidic to neutral water. Active swimmers, they enjoy a varied diet of high-quality flakes, pellets, and live or frozen foods. While breeding can be challenging, these tetras add vibrant color and lively behavior to community aquariums.
