Care & Aquarium Setup

Create a thriving home for your Black Emperor Tetra with a dimly lit, plant-rich aquarium. They prefer gentle currents and clean water. Maintain water parameters around pH 6.5–7.5, temperature 74–82°F (23–28°C), and a weekly water change to keep their environment pristine.

Provide plenty of hiding spots and soft vegetation so they can feel secure while exploring the tank. A well-planted tank with subdued lighting enhances their natural beauty and promotes vibrant color.

Diet & Feeding

In the aquarium, feed a varied omnivorous diet to bring out their best color and energy. Offer high-quality flake or micro pellets supplemented with occasional frozen or live foods like brine shrimp or daphnia. Feed small amounts 1–2 times daily, removing leftovers to keep water pristine.

Tank Mates & Compatibility

They shine in peaceful community setups with other non-aggressive species. Suitable companions include small tetras, rasboras, gouramis, and calm bottom dwellers. Avoid large, aggressive fish that may harass or outcompete them.
