Origin and Distribution

Black Phantom Tetras are indigenous to the upper Paraguay and Madeira river basins in Brazil and Bolivia. They inhabit slow-moving rivers and streams with dense vegetation, providing ample hiding spots and feeding opportunities.

Colors and Markings

This species features a silver-gray body with a distinctive black patch behind the gills, edged with iridescent silver. Males display darker fins, while females have a reddish hue to their pelvic, anal, and adipose fins. The dorsal fin in males is more elongated and erect, especially during displays.

Tankmates

Black Phantom Tetras are peaceful and thrive in community tanks with other non-aggressive species. Suitable tankmates include:

• Other Tetra species
• Rasboras
• Corydoras Catfish
• Small Gouramis
• Livebearers like Guppies and Mollies

It’s advisable to keep them in groups of at least six to promote natural schooling behavior and reduce stress.

Habitat and Care

To replicate their natural environment:

• Tank Size: A minimum of 20 gallons is recommended to accommodate a small school and provide ample swimming space.
• Substrate: Use a dark substrate to enhance their coloration.
• Plants: Incorporate live plants such as Java Fern, Anubias, and floating species to provide cover and mimic their natural habitat.
• Lighting: Moderate lighting is ideal to showcase their features without causing stress.
• Filtration: Ensure efficient filtration to maintain water quality, as they are sensitive to poor conditions.

Regular water changes and monitoring of parameters are essential to keep them healthy.

Diet and Feeding

Black Phantom Tetras are omnivorous and thrive on a varied diet. Offer them:

• High-quality flake or pellet food
• Live or frozen foods like bloodworms, brine shrimp, and daphnia
• Occasional vegetable matter such as blanched spinach or spirulina-based flakes

Feed them small amounts 2–3 times daily, ensuring they consume all the food within a few minutes.

Gender Differences

Males are typically more slender with darker, more pronounced fins, while females are rounder, especially when carrying eggs, and exhibit a reddish hue in their pelvic, anal, and adipose fins.

Breeding

Breeding Black Phantom Tetras in captivity is relatively straightforward:

• Breeding Tank: Set up a separate tank with soft, slightly acidic water and fine-leaved plants or spawning mops.
• Conditioning: Feed breeding pairs a high-protein diet of live and frozen foods to encourage spawning.
• Spawning: After spawning, remove adults to prevent them from eating the eggs.

Eggs typically hatch within 24–36 hours, and fry become free-swimming a few days later. Feed fry infusoria or commercially available fry food until they are large enough to accept baby brine shrimp.
