Neon Tetra Basics: Understanding the Species

Native to South America, neon tetras (Paracheirodon innesi) are stunning freshwater neon tetra fish that bring dazzling color and tranquility to any aquarium. Over 1.5 million neon tetras are imported to the U.S. every month, making them one of the most popular aquarium fish worldwide. Their hardiness, low care needs, and compatibility with other fish make them an ideal choice for novice aquarists looking to start a fish tank.

These small, torpedo-shaped fish are known for their iridescent red stripe that runs from their belly to the tail and their vibrant blue-green stripe above it. In the wild, they grow up to 2.5 inches long and can live up to 4-5 years in a carefully controlled aquarium. Neon tetras are schooling fish, which means they thrive in groups of at least six individuals, providing them with a sense of security, protection, and companionship.

Size & Shape

Neon tetras have the following characteristics:

• Slender, torpedo-shaped body
• Can reach up to 1.5 inches in length in captivity
• Petite fins and durable scales
• Vibrant coloration

These features make them a stunning addition to any aquarium.

The unique appearance of neon tetras is due to guanine crystals found inside their cells that reflect off light, creating a mesmerizing effect.

Distinctive Features

The most noticeable feature of green neon tetras is their vibrant color pattern consisting of a thick iridescent red stripe from the belly to the tail and a blue-green stripe above it. This striking coloration sets them apart from other tetra species, such as cardinal tetras, which have a longer red stripe that runs the entire length of the body.

Male and female neon tetras differ slightly in appearance: males have a sleek body and a vibrant blue neon stripe, while females have a beautiful gradient stripe and a fuller, rounder belly.
