Tetras, including popular types like the Neon Tetra and Cardinal Tetra, are small, vibrant freshwater fish originating mainly from South America. They are admired for their brilliant coloration ranging from vivid reds and blues to iridescent greens. These fish typically grow to about 1-2 inches and thrive in well-planted aquariums with soft, slightly acidic water. Known for their peaceful temperament, tetras are schooling fish that do best in groups of six or more, which helps reduce stress and encourages natural behaviour. Their active and social nature makes them a suitable choice for community tanks with other small, non-aggressive species. Ideal for aquarium enthusiasts in the United Kingdom, tetras are relatively easy to care for, requiring stable water conditions and a varied diet including flakes and occasional live or frozen foods. Search trends such as "neon tetra price pets at home" and "tetras for sale" indicate strong interest in these species, underscoring their popularity among UK fishkeepers seeking lively and colourful additions to their tanks.
