What Red Phantom Tetra look like
The Red Phantom Tetra (Hyphessobrycon sweglesi) exhibits a strikingly deep ruby-red, transparent body that can reach a maximum adult size of approximately 2.5 inches (6.35 cm). This species displays sexual dimorphism, with females typically being slightly larger and rounder than males, particularly when gravid. A notable morphological feature is the dark comma-shaped mark located posterior to the gills, which serves as a distinguishing characteristic. The fins are adorned with white tips, enhancing the overall aesthetic appeal of the fish. Additionally, the Red Phantom Tetra possesses a laterally compressed body shape and a well-developed adipose fin, which contributes to its agile swimming abilities. Defensive adaptations include a schooling behavior that provides safety in numbers, as well as a quick, darting swimming style to evade predators.
Behavior & temperament
Red Phantom Tetras are primarily social fish that thrive in schools, exhibiting a strong tendency to form cohesive groups in the wild. They inhabit the mid to upper water column of their aquatic environments, often found in slow-moving streams and flooded forest areas of the Orinoco River basin. Their breeding behavior is characterized as an egg scatterer, where females release eggs among fine-leaved plants, providing some cover for the developing fry. In terms of temperament, they are generally peaceful but can exhibit mild territoriality during breeding periods, making them suitable for community tanks with similarly sized and temperamented species.
Diet & feeding
In their natural habitat, Red Phantom Tetras are omnivorous, feeding on a varied diet that includes small invertebrates, plant matter, and detritus. In captivity, they require a balanced diet consisting of high-quality flake food, supplemented with live or frozen foods such as brine shrimp and daphnia to ensure optimal health and coloration.
