Cardinal tetra
The cardinal tetra is a species of freshwater fish of the family Acestrorhamphidae, the American characins, of order Characiformes. It is native to the upper Orinoco and Negro Rivers in South America. Growing to about 3 cm (1.2 in) in total length, the cardinal tetra has the striking iridescent blue line characteristic of the genus Paracheirodon laterally bisecting the fish, with the body below this line being vivid red in color, hence the name "cardinal tetra". The cardinal tetra's appearance is similar to that of the closely related neon tetra, with which it is often confused; the neon's red coloration extends only about halfway to the nose, and the neon's blue stripe is a less vibrant blue.

What to Know Before Buying a Cardinal tetra
Finding a responsible Cardinal tetra breeder requires more than browsing classified ads or responding to social media posts. The USDA requires any breeder who sells fishs commercially — especially those selling online or through third-party dealers — to hold a federal license and submit to regular inspections. A legitimate breeder should be willing to provide their USDA license number, invite you to visit their facility, and show you where the animals are housed and socialized.
Before committing to a purchase, ask the breeder for veterinary health records, vaccination documentation, and any genetic testing results relevant to the Cardinal tetra. Reputable breeders will also ask you questions in return — about your living situation, experience with animals, and ability to provide long-term care. A breeder who asks no questions and is eager to ship an animal immediately is a significant red flag.
Use the search tool below to check whether any USDA-licensed facilities breeding Cardinal tetras appear in our database. If they do, review their inspection history carefully. Look for patterns of violations, pay attention to severity levels, and compare their compliance grade with other breeders in the same state. This due diligence takes minutes and can save you from supporting a facility with documented animal welfare problems.
