Description
The Cardinal Tetra is a small, vibrant freshwater fish known for its striking iridescent blue-green stripe running horizontally above a bright red stripe. These peaceful, schooling fish are native to the blackwater rivers of South America and thrive in well-planted aquariums with stable water parameters. They are often confused with the Neon Tetra but have a more extensive red stripe.
