Black Phantom TetraHyphessobrycon megalopterusThe Black Phantom Tetra is an elegant and distinctive South American tetra known for its smoky grey body and the characteristic dark “phantom” patch positioned behind the gill plate. Subtle yet eye-catching, this species adds contrast and movement to planted community aquariums without overwhelming tankmates.Males typically develop longer dorsal fins and slightly deeper coloration, especially when displaying toward one another. These interactions are largely ritualistic and rarely result in harm. When kept in proper groups, Black Phantom Tetras exhibit coordinated schooling behavior and confident mid-water activity.Key Information Maximum Size: Approximately 1.5–1.75 inches Temperament: Peaceful; mild display behavior between males Swimming Level: Mid-water Social Requirement: Best maintained in groups of 6 or more Care Requirements Minimum Aquarium Size: 20 gallons Temperature Range: 72–82 °F pH: 6.0–7.5 Water Hardness: Soft to moderately soft Diet: Omnivorous; accepts quality dry foods, frozen, and live options
