Green Neon Tetra - Paracheirodon simulans : Complete Fish Profile & Care Guide
Table of contents
Introduction
The Green Neon Tetra (Paracheirodon simulans) is not only stunning but also peaceful and easy to care for, making it a great addition to any aquarium. Although it has specific requirements and is not recommended for community aquariums due to its small size, this fish is a great choice for a dedicated aquarium. Maintaining a school of 8 to 10 Green Neon Tetras is essential to bring out their social behaviour and minimize shyness. These Tetras may be peaceful with other species, but it is not the best choice for a community tank due to its unique needs and small size. For optimal care, it is best to keep them with smaller, non-aggressive characids and smaller callichthyid or loricariid catfishes. This will ensure that these beautiful and social fish thrive in their environment and display their vibrant colours to the fullest. This species also has subtle variations that make it a unique choice for aquarists looking for something different. Compared to its closely related and more popular cousin, the Neon Tetra, the Green Neon Tetra has a larger size, a more pronounced green colouration that stretches across its body, and distinct red patches.Green Neon Tetra Photos
Sexual Dimorphism
Distinguishing male from female Green Neon Tetras can be quite a challenge. These fish exhibit similar physical characteristics and colouration, making sexing them a task that requires close attention to detail. However, mature females can typically be identified by their rounder body shape and slightly larger size compared to males.\r\nQuick Facts

Natural Habitat
Green Neon Tetras are native to the Rio Negro and Rio Orinoco systems in Colombia and Venezuela, where they inhabit unique and diverse blackwater environments. Their natural habitats contain a mix of slow to moderately-flowing water with dense overhanging vegetation, sandy substrates covered in leaf litter, fallen branches, and tree roots. The water in their natural habitat is acidic, low in carbonate hardness and conductivity, and stained brown due to the presence of humic substances released by decomposing organic matter. This specific habitat is what sets them apart from other Tetras and is something to consider when creating an ideal environment for them in a home aquarium. These fish thrive in an environment with dense vegetation, dim lighting, and an appropriately adjusted pH level. By providing these conditions, you can replicate their natural environment and enhance their colouration, which is an incredible sight to see.
