Black Emperor Tetra

The Black Emperor Tetra (Nematobrycon palmeri var. black) is a selectively bred variant of the standard Emperor Tetra, Nematobrycon palmeri. It is known for its darker, more dramatic coloration, which sets it apart from the typical metallic hues of its wild-type counterparts.

Characteristics:

• Appearance:

  • Deep black or smoky body coloration.
  • Metallic highlights (blue or green) may be visible under certain lighting conditions.
  • Males are often more vividly colored and have extended fins, while females are generally smaller and less ornate.

• Size: Typically grows to about 45 cm (1.52 inches) in length.

• Behavior:

  • Peaceful and suitable for community tanks.
  • Exhibits shoaling behavior and should be kept in groups of 6 or more.

Habitat:

• Native Region: The Emperor Tetra species originates from Colombia, specifically slow-moving tributaries and streams. However, the Black Emperor Tetra is a captive-bred variant and does not occur in the wild.
• Tank Setup:
  • Mimic natural conditions with subdued lighting, live plants, and dark substrates.
  • Provide hiding spaces using driftwood or rocks.

Water Parameters:

• Temperature: 2227C (7280F)
• pH: 5.07.5
• Hardness: Soft to moderately hard water.

Diet:

Omnivorous and easy to feed. Accepts a variety of foods, including high-quality flakes, micro-pellets, frozen foods (like bloodworms and daphnia), and live foods.

Breeding:

• Easy to breed in a dedicated breeding tank with slightly acidic water.
• Females lay eggs on plants or other surfaces, and males fertilize them externally.
• Parents may eat the eggs, so it’s best to separate them once spawning occurs.

This fish is a striking addition to any aquarium, particularly for enthusiasts looking for an exotic yet manageable species.
