Neon Tetras (Paracheirodon innesi) are one of the most popular and recognizable freshwater fish in the aquarium hobby. They are known for their vibrant blue and red colors, which make them a striking addition to any tank.

Neon Tetras have a slender, torpedo-shaped body and can grow up to about 1.5 inches (3.8 cm) in length. Their bodies are a beautiful iridescent blue, with a bright red stripe running horizontally along their sides. This combination of colors creates a neon-like effect, giving them their name.

These fish are native to the blackwater streams of South America, particularly the Amazon basin. They prefer soft, slightly acidic water conditions that mimic their natural habitat. It's important to maintain the water temperature between 72-78°F (22-26°C) and the pH level around 6.0-7.0 for optimal health.

Neon Tetras are peaceful and social fish, so they should be kept in groups of at least six individuals to ensure their well-being. They feel more secure when in a school, and their colors become more vibrant when they are together. However, they are also small and can be easily preyed upon by larger or aggressive tankmates, so choose their tankmates carefully.

When it comes to feeding, Neon Tetras are omnivorous and will eat a variety of foods. They readily accept high-quality flake or pellet foods designed for small tropical fish. It's also beneficial to supplement their diet with small live or frozen foods like daphnia or brine shrimp to provide them with additional nutrients.

Breeding Neon Tetras can be challenging, as they require specific conditions to induce spawning. Separate breeding tanks with very soft water and low lighting are often necessary. The females scatter their eggs among fine-leaved plants, and the parents should be removed after spawning to prevent them from eating the eggs.

Overall, Neon Tetras are a stunning and peaceful fish that can bring life and color to any community aquarium. With proper care, suitable tank conditions, and adequate tankmates, they can thrive and provide endless enjoyment to their owners.
