Tetras are one of the most popular types of fish for aquarium enthusiasts. They are known for their vibrant colors and peaceful temperament, which make them great additions to community tanks. If you are thinking of adding tetras to your aquarium, it is important to understand their schooling behavior and how to properly care for them.
Tetras are schooling fish, which means they thrive when kept in groups of at least six or more. When kept in a group, tetras feel more secure and are less stressed. This also allows them to display their natural behavior, such as swimming in unison and playing together. If kept alone or in small numbers, tetras can become shy and reclusive, which can lead to health issues.
When choosing tetras for your aquarium, it is important to consider their size and temperament. There are many different types of tetras, including neon tetras, cardinal tetras, black skirt tetras, and more. Neon tetras are one of the most popular types of tetras, known for their bright blue and red colors. Cardinal tetras are similar to neon tetras, but have a deeper red color. Black skirt tetras are larger and have a more subdued coloration.
Once you have selected your tetras, it is important to properly acclimate them to their new environment. This involves slowly introducing them to the water temperature and chemistry in your aquarium.
