Tetra

Tetras are a diverse group of small, colorful freshwater fish that belong to the family Characidae. They are popular among aquarium hobbyists due to their vibrant colors, active behavior, and peaceful nature. Tetras come in a variety of species, each with its own unique characteristics. Here’s a general description of tetras:

Appearance: Tetras have a slender and elongated body shape, which is often slightly compressed laterally. They come in various colors and patterns, making them visually appealing. Many tetra species have vibrant shades of red, blue, green, orange, or yellow, often accompanied by striking patterns or markings. Their fins may be transparent or display bold colors, adding to their overall beauty.

Size: The size of tetras varies depending on the species. Generally, they range from around 1 to 3 inches (2.5 to 7.5 cm) in length, with some species being slightly larger or smaller.

Behavior: Tetras are known for their peaceful and non-aggressive behavior, making them excellent candidates for community aquariums. They are social fish that thrive when kept in groups of at least six or more individuals. In a school, tetras feel more secure and exhibit their natural schooling behavior, creating a beautiful display of synchronized swimming.

Water Requirements: Tetras are adaptable to a range of water conditions. However, they generally prefer slightly acidic to neutral water with a pH level ranging from 6.0 to 7.5. The temperature should be maintained between 72°F and 80°F (22°C to 27°C). Providing clean, well-filtered water and regular water changes is important for their overall health and well-being.

Feeding: Tetras are omnivorous and have a versatile diet. They readily accept high-quality dry foods such as flakes or pellets. However, it’s beneficial to supplement their diet with live or frozen foods like brine shrimp, bloodworms, daphnia, or small insects. Offering a varied diet ensures proper nutrition and enhances their colors.

Aquarium Setup: Tetras are relatively small and can be kept in aquariums of various sizes, depending on the species and the number of fish. They appreciate a well-planted aquarium with plenty of swimming space. Providing driftwood, rocks, and live plants creates natural hiding spots and mimics their natural habitat. Tetras prefer a peaceful community aquarium, and care should be taken when selecting tank mates to ensure compatibility.
