1 Tetras Fish for sale in Cambridge, Cambridgeshire

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.

FAQs

How many tetras should be kept together?

Tetras are schooling fish and should be kept in groups of at least six to promote natural behaviour and reduce stress, though groups of 10-12 or more are ideal for optimal schooling activity and welfare.

Why are tetras sometimes considered hard to keep?

Tetras are generally easy to care for but can require specific conditions such as stable tropical water temperatures with a heater, proper water parameters, and secure tanks to prevent jumping; sensitivity to water changes and social needs make them somewhat challenging without proper care.

What is considered the prettiest tetra?

While subjective, cardinal tetras are widely regarded as the prettiest due to their vibrant red and blue colours, closely followed by neon tetras which are also admired for their bright iridescent markings.

How aggressive are tetras?

Most tetras are peaceful and non-aggressive, ideal for community aquariums; however, some species may occasionally nip fins if the male-to-female ratio is unbalanced or if kept in too small numbers.
