The Cardinal Tetra (Paracheirodon axelrodi) is a strikingly beautiful and popular freshwater fish, highly sought after for its vibrant colors and peaceful demeanor. Originating from the clear, slow-moving waters of the Amazon basin, particularly in Brazil, Colombia, and Venezuela, these small characins are a true jewel of the aquarium. They are distinguished by a brilliant iridescent blue-green stripe running horizontally along their flanks, perfectly complemented by a vivid scarlet-red stripe beneath it, extending from the snout to the caudal fin. This intense red coloration is more pronounced and covers a larger area than in their close cousin, the Neon Tetra. Growing to about 2 inches (5 cm), Cardinal Tetras are ideal for planted aquariums and thrive in soft, acidic water conditions that mimic their natural blackwater habitats. They are schooling fish by nature, and keeping them in groups of six or more will not only reduce stress but also enhance their dazzling display, as their synchronized movements create a mesmerizing, living ribbon of color. While generally hardy, they prefer stable water parameters and are sensitive to sudden changes. They are omnivores, readily accepting high-quality flake foods, micro-pellets, and frozen or live brine shrimp and daphnia, which will further intensify their colors. Their peaceful temperament makes them excellent community tank inhabitants, coexisting well with other small, non-aggressive species like Rasboras, Corydoras, and Dwarf Cichlids. A well-maintained tank with plenty of live plants and subdued lighting will bring out the best in these magnificent fish, making them a breathtaking centerpiece for any aquarist.

Slightly larger and more sensitive than Neons.
