About Black Phantom Tetra

The black phantom tetra is a sophisticated-looking fish from the upper Paraguay and Guapore river basins in Brazil and Bolivia. Males are smoky gray-black with dramatically tall dorsal and anal fins that they spread wide during territorial displays, creating an impressive phantom-like silhouette. Females contrast beautifully with reddish-brown bodies and red-tinted fins. Males frequently engage in ritualized sparring displays, circling each other with fins fully extended in a dance-like confrontation that rarely results in any actual contact. This species is a refined alternative to more common tetras, offering subtle beauty and interesting social behavior in the community aquarium.

Care Tips

Expert Tips

Keep black phantom tetras in groups of at least six, with a balanced mix of males and females to observe their fascinating display behaviors. Males will frequently spar with each other in harmless fin-spreading contests. They prefer soft, slightly acidic water at 72-82°F with some tannins from driftwood or dried leaves. A dark substrate and background make their subtle coloring and dramatic fin displays stand out. They are peaceful with other species and make excellent companions for other tetras, rasboras, and corydoras. Feed a varied diet of quality flakes and frozen foods.
