Tetras are like the sparkling gems of freshwater aquariums. They’re small, vibrant, and full of life, often lighting up any tank with their brilliant colors and energetic swimming. Think of them as the perfect starter fish but also adored by seasoned aquarists because they’re pretty easy to care for. They thrive in groups, making a visually stunning display with their tight, synchronized movements. Ideal for community tanks, tetras generally get along with other peaceful fish, adding dynamism without the drama. Whether you’re setting up your first aquarium or looking to add some color to an existing setup, tetras are a fantastic choice.
