Black Lined Costae Tetra 3cm (Group of 10)

The Black Lined Costae Tetra (Moenkhausia costae) is a striking and lesser-known tetra from the São Francisco River basin in Brazil. Displaying a sleek silver body with a bold black horizontal stripe running from the snout to the tail, it is a clean, elegant species that stands out beautifully in planted aquariums. Hardy and peaceful, it is an excellent choice for hobbyists looking for something a little different from the usual tetra lineup.
