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.

Pearl gouramis are widely considered the most beautiful gourami species, with a body covered in iridescent pearl-like spots over a brown-silver base. Males develop a stunning red-orange chest and throat during breeding displays. They are one of the most peaceful gouramis, making them excellent centerpiece fish for community tanks.
