Cardinal Tetra is little freshwater fish belonging to the tetra family.
They have eye-catching colors and calm personalities, Cardinal Tetras can reach a maximum length of two inches. These fish are lively and perfect for tanks with other fish.
Due to their similar look, Neon tetras and Cardinal tetras are frequently confused.
Cardinal tetras (Paracheirodon axelrodi) are found in the Orinoco and Negro Rivers in South America, which cut across Brazil, Colombia, and Venezuela.
In the wild, blackwater creeks and their tributaries are home to cardinal tetras. These water sources are soft, acidic, and dark in color because of the tannins in decomposing leaves.
The cardinal tetra is common in the wild, and the majority of cardinal tetras sold as pets are from wild capture.
