Consequently, it suits hobbyists seeking lively, low-maintenance fish. Let’s dive into creating the perfect setup for this captivating tetra!

Size and Lifespan

Black Widow Tetras grow to about 5cm, with hybrids slightly larger. Additionally, they live around 3–5 years with proper care. Therefore, providing a stable environment ensures their longevity. Their compact size suits various tank setups, making them ideal for beginners and seasoned aquarists alike.

Ideal Tank Setup

Creating a natural habitat keeps the Black Widow Tetra 10 Pack healthy and vibrant. Since they come from shaded, slow-moving waters, mimic these conditions for optimal well-being. Furthermore, a well-planned tank promotes their active schooling behavior.

• Tank Size: Minimum 75 liters for a school of 6–10.
• Water Parameters: pH 6.0–7.5, temperature 22–26°C, soft water.
• Decor: Add plants, driftwood, and shaded areas to replicate forest canopies.
• Filtration: Gentle flow to mimic slow tributaries.

Compatible Tank Mates

Black Widow Tetras thrive with similar-tempered species. However, avoid slow-moving or long-finned fish, as they may nip. Instead, choose robust, peaceful companions to create a harmonious community tank. Suitable tank mates include:

• Other tetras (e.g., Neon, Congo).
• Rasboras.
• Small barbs.
• Corydoras catfish.

Diet and Feeding

These omnivores eagerly accept various foods, ensuring a balanced diet is simple. For instance, offer high-quality flakes, brine shrimp, and worms. Additionally, include vegetable supplements like spirulina for optimal health. Feed them twice daily, providing only what they consume in a few minutes to avoid overfeeding.

Breeding and Behaviour of Black Widow Tetra

Black Widow Tetras exhibit fascinating schooling behavior, moving in sync for a stunning display. Moreover, they breed as egg-layers, scattering eggs among plants. However, they may eat their eggs, so separate breeding pairs in a dedicated tank. Their occasional fin-nipping tendency decreases in larger groups, promoting peaceful interactions.
