Tetras are small freshwater fish that belong to the family Characidae, commonly known as the characins. They are characterized by their vibrant colors, active nature, and schooling behavior. Tetras are native to South America, particularly the Amazon River basin, and are popular among aquarium enthusiasts worldwide.
In terms of physical appearance, tetras typically have streamlined bodies with a forked tail and upturned mouths. They possess an array of stunning colors, ranging from vibrant reds, blues, and greens, to more subtle silver and black hues. The fins of tetras are often elongated, which enhances their graceful swimming movements.
Tetras are social fish and thrive best when kept in groups of at least six individuals. They are known for their peaceful temperament, making them suitable tank mates for a variety of other freshwater species. Tetras display a remarkable schooling behavior, constantly swimming together in coordinated patterns to protect themselves against predators.
As omnivorous creatures, tetras have a varied diet consisting of both plant matter and small invertebrates. In captivity, they can be fed a combination of high-quality flakes, pellets, and live or frozen foods to ensure a balanced and nutritious diet.
Due to their striking appearance, peaceful nature, and ease of care, tetras are popular choices for both beginner and experienced aquarists. Their vibrant colors create a visually appealing display in home aquariums, making them a sought-after species in the ornamental fish trade.
