Neon Tetra - Paracheirodon innesi : Complete Fish Profile & Care Guide

Introduction

The Neon Tetra (Paracheirodon innesi) holds a special place in the hearts of aquarium enthusiasts, captivating novices and seasoned hobbyists alike with its dazzling array of colours. Adorned with shimmering iridescent blue and red stripes that come alive under the right lighting conditions, it's no surprise that this species enjoys enduring popularity.

Beyond their visual allure, Neon Tetras are prized for their resilience and affordability, making them an ideal choice for those new to the hobby. These sociable creatures thrive in the company of their own kind and are best kept in groups of six or more. Larger shoals of eight to twelve individuals allow for a more vibrant display of their natural behaviours, with their striking blue and red stripes creating a mesmerizing spectacle as they move in unison. Conversely, solitary existence can induce stress and compromise their overall health and well-being.

When choosing tank mates for Neon Tetras, it's crucial to select non-aggressive species of similar size. Pairing them with other Tetra species can result in a beautiful, diverse community aquarium. However, they can also share a tank with various other fish species, provided there are no larger or more aggressive fish that might bully or prey on them.

Within a community aquarium, Neon Tetras typically occupy the middle to lower strata, swimming and exploring their surroundings actively. They often shoal together with Cardinal Tetras, their close relatives. A shoal of Neon Tetras enhances the aquarium's beauty while also promoting a healthier, happier environment for these fascinating fish.

To fully appreciate Neon Tetras, it's beneficial to emulate their natural Amazonian habitat in your aquarium. Dense planting offers shelter and security, echoing the lush vegetation of their native environment. Driftwood roots and branches add to this environment, creating a natural backdrop for these luminous fish. For a more authentic look, consider incorporating dried leaf litter into the substrate, which provides additional hiding places.

In terms of lighting, a dimmer setting is optimal to mimic the dappled sunlight of their natural habitat. However, you can still include hardy aquatic plants that thrive in these conditions. Floating plants offer additional cover and foster a more immersive environment for your Neon Tetras.

Neon Tetras are easily recognized by their slender, torpedo-shaped bodies. Each side features a dazzling blue stripe that runs horizontally from the nose to the adipose fin, while a red stripe begins at the mid-body and extends to the base of the caudal fin. Except for these stripes, their fins and bodies are transparent, contributing to their distinct look.

Intriguingly, Neon Tetras' vibrant blue and red stripes turn to shades of grey or black as they rest during the night. This colour change is a response to lighting conditions. In a light-adapted state, the stripe appears blue-green; when dark-adapted, it transforms into indigo. This phenomenon occurs due to guanine crystals in their cells reflecting light, creating a spectacular colour display.

Aquarists can choose from several distinct varieties of Neon Tetras. The semi-albino Golden strain features a unique gold-coloured body, while the rare Long-finned Neon Tetra is characterized by elongated fins. The Diamond Neon Tetra, with metallic scales gleaming on the upper part of its body, adds an alluring shimmer to its appearance.
