The Black Neon Tetra (Hyphessobrycon herbertaxelrodi) is a species of small freshwater fish that is popular in the aquarium hobby due to its striking appearance and peaceful temperament.
Here are some key facts about the Black Neon Tetra:
Appearance
Size: They typically grow to about 1.5 inches (4 cm) in length.
Coloration: The most distinguishing feature is their black horizontal stripe that runs from the nose to the tail, giving them their name. They also have a faint neon blue glow that contrasts with the black stripe, similar to other "neon" species, though not as bright.
Shape: Their bodies are small, slender, and somewhat torpedo-shaped, allowing them to move quickly through the water.
Habitat
Origin: Black Neon Tetras are native to the Rio Paraguay basin in South America, particularly in Brazil, Paraguay, and Argentina.
Water Conditions: They prefer slightly acidic to neutral water with a temperature range of 72-80°F (22-27°C). They thrive in soft to moderately hard water.
Aquarium Setup: These fish do well in well-planted tanks with soft lighting, as they naturally inhabit shaded waters in the wild.
Behavior
Temperament: Black Neon Tetras are peaceful and social fish. They prefer to be kept in schools of at least six individuals, which helps reduce stress and promote natural schooling behavior.
Compatibility: They are compatible with many other small, peaceful species like other tetras, rasboras, and Corydoras catfish.
Diet
Food Preferences: Black Neon Tetras are omnivores. They eat a variety of foods, including high-quality flakes, micro pellets, live or frozen foods like daphnia, brine shrimp, and small worms.
Feeding Tips: It's best to offer them a variety of foods to keep them healthy and vibrant.
Breeding
Breeding Difficulty: They are relatively easy to breed in a home aquarium, though providing a separate breeding tank with soft, slightly acidic water and dense planting is helpful.
Spawning: Female Black Neons usually lay their eggs on plants, and the eggs hatch in a few days. Once the eggs hatch, the fry are tiny and require infusoria or liquid fry food until they are large enough to eat powdered foods.
These fish are beautiful and easy to care for, making them a favorite for beginner and experienced aquarists alike.
