Profile Black Phantom Tetra
Area of origin:
The black phantom tetra lives in slow-flowing, densely vegetated waters in South America. The water is often soft, slightly acidic and shady due to plant growth.
Species:
The black phantom tetra offered in the trade is predominantly Hyphessobrycon megalopterus.
Other "phantom" species are e.g:
- Red phantom tetra (Hyphessobrycon sweglesi)
- White phantom tetra (Megalamphodus megalopterus var.)
The species frequently offered in pet shops include
- Black phantom tetra (standard form)
Rarer:
- Longfin variant
Social behaviour:
The black phantom tetra is peaceful and displays beautiful courtship and display behaviour within the school - the males in particular show off their large dorsal fins. It is ideal for community aquariums with other calm species.
Keeping conditions:
Well-planted aquarium with free swimming zones. Darkened areas (roots, floating plants) preferred. Gentle current. Stable water values and regular water changes. Dark substrate makes the colours appear stronger.
Breeding:
Free spawners - the eggs are scattered over plants or spawning substrates. Parents eat the spawn → breeding tank necessary. Soft, slightly acidic water promotes spawning success. Fry are very small and require infusoria/small food.
Special features:
Very peaceful and ideal for community tanks Males like to show off with fanned-out fins Colours look particularly intense in shady, darker aquariums Robust and well suited for beginners
Conclusion:
The black phantom tetra is an elegant, peaceful schooling fish that particularly comes into its own in well-planted aquariums with soft light. Its harmonious nature and beautiful contrasting colours make it an ideal inhabitant for many community aquariums.
