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.

Puntigrus tetrazona
Tiger barbs are energetic, boldly-striped schooling fish that add constant motion and personality to aquariums. Their orange body with four distinctive black vertical stripes is instantly recognizable. They are notorious fin nippers when kept in small groups, but this behavior is easily managed by keeping 8+ together in a spacious tank.
