The Black Neon Tetra is a peaceful, small freshwater fish known for its striking black and white horizontal stripes and its iridescent green or golden upper body. These eye-catching features, combined with their schooling behavior and hardy nature, make them a favorite choice for both beginner and experienced aquarists. Black Neon Tetras are active swimmers that thrive in community tanks and add a touch of elegance to planted aquariums. They typically grow to about 1.5 inches (4 cm) and can live 5-8 years with proper care.
Habitat and Tank Requirements:
In the wild, Black Neon Tetras inhabit slow-moving, tannin-rich waters with dense vegetation. In aquariums, they thrive in similar conditions that mimic their natural habitat.
Tank Size and Water Parameters:
| PARAMETER | RECOMMENDED |
|---|---|
| Tank Size | Minimum 40 litres |
| Temperature | 72-82°F (22-28°C) |
| pH | 5.5-7.5 |
| Hardness | Soft to moderately hard water, 2-15 dGH |
A well-planted tank with soft, dim lighting helps Black Neon Tetras feel secure and enhances their coloration. Use plants like Java fern, Amazon swords, or floating plants to create shaded areas. A dark substrate and driftwood help replicate their natural environment, and a gentle filter ensures clean water without excessive currents.
