What Blueberry Tetra look like
The Blueberry Tetra (Hyphessobrycon wadai) exhibits a laterally compressed, fusiform body shape, reaching a maximum adult size of approximately 1.5 to 2 inches (3.8 to 5.1 cm). This species is characterized by its striking vivid blue-purple coloration, which serves as a primary distinguishing feature, reminiscent of ripe blueberries. The body is adorned with a subtle iridescent sheen, enhancing its visual appeal. Sexual dimorphism is not pronounced, though males may exhibit slightly more intense coloration compared to females. The Blueberry Tetra possesses a small, forked caudal fin and a well-defined adipose fin, contributing to its streamlined appearance. Its dentition consists of small, conical teeth suited for an omnivorous diet, and it features a lateral line system that aids in detecting movement and vibrations in the water column. Defensive adaptations include its schooling behavior, which provides safety in numbers, and its ability to quickly dart away from potential threats.
Behavior & temperament
The Blueberry Tetra is a social species that thrives in groups, exhibiting a strong tendency to form schools in the mid to upper water column of their aquatic environment. They are generally peaceful and exhibit a calm temperament, making them suitable for community tanks. In the wild, they inhabit slow-moving streams and rivers in South America, where they can be found among submerged vegetation and leaf litter. Breeding behavior involves egg scattering, where females release eggs over a substrate, and males fertilize them externally. The species does not exhibit parental care post-spawning, and the fry are left to fend for themselves. Their social hierarchy is relatively egalitarian, with no significant aggression displayed towards tank mates.
Diet & feeding
In their natural habitat, Blueberry Tetras are omnivorous, feeding on a varied diet that includes small invertebrates, plant matter, and detritus. In captivity, they thrive on high-quality flake foods, supplemented with live or frozen foods such as daphnia and brine shrimp to ensure a balanced diet.
