At first sight, this species may be confused with P. axelrodi (Cardinal Tetra). However, in the Neon Tetra, the red body coloration occupies only the posterior half of the body, while in P. axelrodi it extends from head to tail. Traditionally, there have been two major sources of neons: wild-caught specimens from South America and captive-bred stocks from Hong Kong. However, other sources of captive-bred fish are becoming established, particularly in Sri Lanka. Several cultivated varieties of Neon are available in addition to the wild type, including Diamondhead, Gold, Albino, Brilliant, and “Mon Cheri” (yellow).
