Emperor Tetra (Nematobrycon palmeri)

The Emperor Tetra is a striking, mid-sized schooling fish known for its iridescent blue body, elongated fins, and bold black horizontal stripe along the body. Its graceful swimming style and vivid colours make it a favourite for planted community aquariums.

Origin:
Native to Colombia, particularly the San Juan and Atrato River basins, Emperor Tetras inhabit slow-moving, shaded waters with abundant vegetation.

Behaviour & Tank Role:

• Peaceful and active, best kept in groups of 6 or more.

• Mid-to-top dwelling schooling fish that add movement and colour to community aquariums.

• Compatible with other non-aggressive fish of similar size; avoid fin-nipping species.

Care Requirements:

• Tank Size: 80L+ recommended for a small school.

• Temperature: 22–26°C

• pH: 6.0–7.5

• GH: 4–12 dGH

• TDS: 100–200 ppm

• Provide a planted environment with open swimming areas and hiding spaces; moderate water flow preferred.

Feeding:
Omnivorous: accept high-quality flake or micro pellets, supplemented with frozen/live foods such as daphnia, brine shrimp, or bloodworms. Feed in moderation and remove uneaten food to maintain water quality.

Breeding Tips:

• Egg scatterers that prefer dimly lit tanks with fine-leaved plants or spawning mops.

• Separate adults after spawning to protect eggs.

• Eggs hatch in 3–4 days; fry can be fed infusoria or microfoods before transitioning to baby brine shrimp.

• Stable water chemistry (soft, slightly acidic) improves breeding success.

Why Choose Emperor Tetras?
Their vibrant colours, elegant swimming behaviour, and peaceful temperament make Emperor Tetras a standout choice for planted and community aquariums. They are both visually striking and easy to care for, suitable for beginners and experienced aquarists.
