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).
- Hyphessobrycon innesi
- Putumayo River, eastern Peru.
- Around 1 1/2in (4cm).
- Peaceful shoaler.
- Wide range of foods accepted.
- Well planted, with some open spaces and subdued lighting (e.g. provided by floating plants), recommended. These fish are often, but not invariably, found in tannin-stained water. Soft, acid water recommended, but harder, more alkaline conditions tolerated if adjustments carried out gradually. Temperature range: 68-79 F (20-26 C).
- Challenging in aquaria. Subdued lighting and very soft, acid, tannin-stained water will enhance chances of success. Eggs are scattered among vegetation and may be eaten by the parents Hatching takes about 1 day.
