The Black Phantom Tetra (Hyphessobrycon megalopterus) is a small, peaceful, and attractive freshwater fish native to the rivers of South America, specifically found in the regions of Brazil, Paraguay, and Argentina. It's a popular choice among aquarium enthusiasts due to its striking appearance, ease of care, and peaceful nature, making it a great addition to a community aquarium.
Key Characteristics of Black Phantom Tetra:
Size: Grows to about 1.5–2 inches (4–5 cm) in length.
Coloration: The males are known for their deep black body color with a characteristic dark triangle at the back of their body. The females are typically lighter in color with a more silver or pale hue. Both males and females have a distinctive black fin pattern, and their bodies shimmer with iridescence, making them stand out in the aquarium.
Lifespan: 3–5 years with proper care.
Behavior: Peaceful, calm, and non-aggressive. Black Phantom Tetras are social fish and should be kept in groups to feel secure.
Activity Level: Moderate; they are active swimmers but tend to swim in the middle to top layers of the tank.
Water Parameters for Black Phantom Tetra:
Temperature: 22–28°C (72–82°F), as they prefer warm water.
pH: 6.0–7.5, slightly acidic to neutral water.
Hardness: 4–15 dGH, though they can adapt to a range of water hardness.
Tank Size: A minimum of 10 gallons for a small group. For a group of 6 or more, a 20-gallon tank is ideal.
Tank Setup for Black Phantom Tetra:
Substrate: Fine gravel or sand works best for the Black Phantom Tetra. A darker substrate enhances their natural coloration.
Plants: Live plants such as Java fern, Anubias, and Amazon sword are great for providing hiding spots and natural cover. Floating plants can also provide some shaded areas.
Lighting: Moderate lighting is best. Too much light can stress the fish, so a subdued, natural lighting setup works well.
Water Flow: A gentle to moderate water flow is ideal. Strong currents can stress these fish, as they prefer calm waters.
Decor: Use driftwood, rocks, and plants to create hiding spaces. Black Phantom Tetras appreciate a tank that offers a variety of hiding spots.
Diet:
Black Phantom Tetras are omnivores and will accept a variety of foods:
Staple Foods: High-quality fish flakes or pellets, which should form the bulk of their diet.
Protein Sources: Live or frozen foods such as brine shrimp, daphnia, and bloodworms.
Vegetable Matter: Blanched vegetables like spinach, zucchini, or spirulina-based flakes.
Feeding Tip: Feed small portions 2–3 times a day. Since they are small fish, be sure to provide a variety of foods to meet their nutritional needs.
Behavior and Tankmates:
Behavior: Black Phantom Tetras are peaceful and enjoy the company of their own kind. They should be kept in groups of at least 6 or more to help them feel secure and reduce stress. They are generally non-aggressive but may show some mild territorial behavior when breeding.
Tankmates:
Compatible Species: Peaceful fish such as neon tetras, cardinal tetras, rasboras, Corydoras catfish, and dwarf gouramis. They also get along with small, non-aggressive barbs and peaceful livebearers.
Avoid: Aggressive or fin-nipping fish such as bettas, larger cichlids, or tiger barbs, as they could cause stress or harm the Black Phantom Tetras.
Breeding Black Phantom Tetra:
Breeding Black Phantom Tetras can be done in a separate breeding tank to help protect the eggs from other tankmates. The breeding process is fairly straightforward:
Breeding Tank: Set up a separate breeding tank with soft, slightly acidic water (pH around 6.0–6.5) and provide plants or spawning mops where the female can lay her eggs.
Conditioning: Feed the breeding pair live foods like brine shrimp or bloodworms to condition them for spawning.
Spawning Behavior: Males will chase the female around the tank, displaying their vibrant colors. The female will release the eggs, which the male fertilizes.
Egg Care: After spawning, remove the parents to prevent them from eating the eggs. The eggs typically hatch in 24–48 hours.
Fry Care: The fry can be fed infusoria or specially prepared liquid fry food until they are large enough to eat crushed flakes or baby brine shrimp.
Care Tips:
Group Size: Keep at least 6 Black Phantom Tetras together to ensure they feel secure and reduce stress. They are social fish and thrive in groups.
Water Quality: Perform regular water changes (about 20–30% each week) to maintain good water quality, as these fish are sensitive to poor water conditions.
Tankmates: Choose peaceful fish for community tanks to prevent stress and aggression.
Environment: Provide plenty of plants, both floating and rooted, as well as hiding spots to create a natural and secure environment.
