Cardinal Tetra

Cardinal Tetra £2.09 The Cardinal Tetra is one of the most widely recognised species in the hobby. Similar in appearance to the Neon Tetra, it is the stronger of the two. Visually, the primary difference between the two is that cardinals have the red line run the entire length of the body, whilst neons have it only half way. They can be a little less forgiving when it comes to water hardness and pH, but tend to be a lot less prone to genetic shortcomings.
