Neon Tetra

Paracheirodon innesi

The Neon Tetra (Paracheirodon innesi) is a small, vibrant freshwater fish native to the warm tributaries of the Amazon Basin in South America, particularly in Peru, Colombia, and Brazil. Known for its striking appearance, the Neon Tetra showcases a remarkable iridescent blue body that casts a shimmering glow, contrasted by a vivid red stripe running from mid-body to the tail. This vivid coloration serves as both a means of communication and a defense mechanism, helping them thrive in their natural, dimly lit aquatic environments. Growing to an average size of 1.5 inches (around 3.8 cm), Neon Tetras are popular among aquarists for their peaceful nature and schooling behavior, preferring to swim in groups for safety and social interaction. They thrive in warm, soft, and slightly acidic water conditions, closely resembling their native habitats. These omnivorous fish have a diet that includes small invertebrates, algae, and plant matter. Due to their hardiness and striking colors, Neon Tetras have become a staple in the tropical fish trade, valued by hobbyists worldwide for their beauty and low-maintenance care requirements.
