Species Profiles
Cardinal Tetra
Paracheirodon axelrodi
Cardinal tetras look similar to neon tetras but have a red stripe that extends the entire length of their body (vs only the back half in neons). They prefer softer, more acidic water and are slightly more delicate, but their deeper coloration makes them highly sought after.
