What Scratched Inpa Tetra look like

Inpaichthys parauapiranga, commonly known as the Scratched Inpa Tetra, exhibits a laterally compressed, fusiform body shape typical of the Tetra family. Adults can reach a maximum size of approximately 2 inches (5 cm), with males often displaying more pronounced iridescent blue-purple coloration compared to females. The species is characterized by distinctive dark markings that create a 'scratched' pattern along the flanks, particularly evident in males, which enhances their visual appeal. The presence of a well-defined lateral line aids in hydrodynamic sensing, while the small, forked caudal fin and elongated dorsal fin contribute to their agile swimming capabilities. Defensive adaptations include a schooling behavior that reduces individual predation risk, and their coloration may serve as camouflage among aquatic vegetation.

Behavior & temperament

The Scratched Inpa Tetra is a social species that thrives in small to medium-sized schools, exhibiting a hierarchical structure within groups. They primarily inhabit the mid-water column, displaying a preference for densely vegetated areas where they can seek refuge from potential predators. Breeding behavior is characterized by egg scattering, where females release eggs among plants, ensuring some are hidden from predation. Their temperament is generally peaceful, making them suitable for community tanks, although males may exhibit territorial behaviors during breeding periods.

Diet & feeding

In the wild, the Scratched Inpa Tetra is an omnivore, feeding on a varied diet that includes small invertebrates, plant matter, and detritus. In captivity, they require a balanced diet of high-quality flake food, supplemented with live or frozen foods such as brine shrimp and daphnia to ensure optimal health and coloration.
