What Yellow Phantom Tetra look like
The Yellow Phantom Tetra (Hyphessobrycon roseus) exhibits a laterally compressed, fusiform body that typically reaches a maximum adult size of approximately 2 inches (5 cm). Its most distinguishing feature is its translucent pale golden-yellow coloration, which gives it an ethereal appearance, often described as 'phantom-like.' The body is semi-transparent, allowing for a subtle interplay of light that highlights its delicate and elegant form. The dorsal fin is moderately sized and triangular, while the anal fin is elongated and pointed, contributing to its streamlined silhouette. The species lacks pronounced sexual dimorphism, though females may appear slightly fuller when gravid. Defensive adaptations include a tendency to school in groups, which reduces individual predation risk. The presence of a lateral line system aids in detecting water movements, enhancing its ability to navigate its environment effectively.
Behavior & temperament
Hyphessobrycon roseus is a social fish that thrives in small to medium-sized schools, exhibiting a peaceful temperament that makes it suitable for community tanks. It typically occupies the mid to upper levels of the water column, where it engages in active swimming and foraging behaviors. The species is known for its non-aggressive nature, often displaying a calm demeanor even in the presence of other species. Breeding behavior is characterized by egg scattering, where females release eggs in open water, allowing them to adhere to vegetation or substrate. This reproductive strategy is complemented by a communal spawning behavior, where multiple pairs may breed simultaneously in a well-planted aquarium.
Diet & feeding
In the wild, the Yellow Phantom Tetra is an omnivore, feeding on a varied diet that includes small invertebrates, algae, and plant matter. In captivity, it requires a balanced diet consisting of high-quality flake food, supplemented with live or frozen foods such as brine shrimp and daphnia to maintain optimal health and coloration.
