Tetras are known for their vibrant colors and peaceful nature, making them a great addition to community aquariums. These small, active fish are best kept in schools of at least 6 or more to keep them happy and healthy. Tetras do best in well-planted aquariums with moderate lighting.

One of the unique features of tetras is their bioluminescent ability, which makes them glow under certain lighting conditions. This phenomenon is caused by specialized cells in their skin called iridophores. The shimmering effect is particularly pronounced in certain species, such as the neon tetra.

It’s important to introduce Tetras in stable aquariums; this means cycling the tank with hardier fish fist to establish the beneficial bacteria needed to break down harmful waste products, such as ammonia and nitrite, and create a healthy environment for fish to thrive.

Tetras come in a wide range of species, each with its own unique characteristics and requirements. Some of the most popular species include neon tetras, cardinal tetras, and black skirt tetras. Overall, tetras are an excellent choice for enthusiasts looking to add color and social activity to their community aquarium.
