Hyphessobrycon megalopterus, commonly known as the Black Phantom Tetra, is a peaceful and visually striking freshwater fish, popular among aquarists for its distinct coloration and social behavior.
Overview
Hyphessobrycon megalopterus, commonly known as the Black Phantom Tetra, is a small and peaceful freshwater fish that originates from the river basins of Bolivia and Brazil. It is well-known for its unique appearance, with males displaying a dark, almost black dorsal fin and a smoky-gray body, while females are paler with red accents. This species grows to about 4-5 cm (1.5-2 inches) in length and is popular among aquarists for its social nature and compatibility with other peaceful community fish.
Tank Requirements
Black Phantom Tetras thrive in an aquarium that mimics their natural environment with plenty of plants, driftwood, and open swimming areas. A tank of at least 70 liters (20 gallons) is recommended to house a small school of these tetras, as they are a shoaling species that feel most secure in groups of six or more. The water temperature should be kept between 22-28°C (72-82°F), with a pH of 6.0 to 7.5 and a general hardness (GH) of 4-18. A dark substrate and subdued lighting will enhance their colors and reduce stress.
Feeding and Diet
Hyphessobrycon megalopterus is an omnivorous species that will accept a wide variety of foods in captivity. A diet consisting of high-quality flake food, small pellets, and frozen or live foods such as daphnia, bloodworms, and brine shrimp will help to keep them healthy and enhance their coloration. Feeding them a varied diet will also encourage natural foraging behavior and ensure they receive all the necessary nutrients.
Care and Maintenance
The Black Phantom Tetra is relatively easy to care for and is a good choice for beginner aquarists. Regular water changes and maintaining stable water parameters are essential to prevent stress and disease. This species is generally hardy, but it can be susceptible to common freshwater fish diseases if water quality is poor. As a peaceful fish, it should be kept with other non-aggressive species of similar size to prevent fin nipping or stress.
Compatibility
Black Phantom Tetras are peaceful and do well in a community tank with other small, non-aggressive fish such as other tetras, rasboras, and small catfish. They are known for their playful behavior and social interactions within their group, often engaging in mock battles and displays, especially among males. Keeping them in a school not only promotes natural behavior but also adds a dynamic visual element to the aquarium.
Breeding
Breeding Hyphessobrycon megalopterus in captivity is relatively straightforward, provided that the water conditions are optimal and the fish are well-conditioned. A separate breeding tank with soft, slightly acidic water (pH 6.0-6.5) and a temperature of around 26°C (79°F) is recommended. The tank should be densely planted or include a spawning mop to protect the eggs. Males will display to females and perform courtship dances, leading to the scattering of eggs. After spawning, the parents should be removed to prevent them from eating the eggs. The eggs will hatch in about 24-36 hours, and the fry can be fed infusoria or liquid fry food until they are large enough to accept baby brine shrimp or finely crushed flakes.
