Pretty Tetra Care Guide
Hemigrammus pulcher · Freshwater Fish
What Pretty Tetra look like
Hemigrammus pulcher, commonly known as the Pretty Tetra, exhibits a laterally compressed, fusiform body shape, typically reaching a maximum adult size of approximately 2 inches (5 cm). The species displays sexual dimorphism, with males often exhibiting more vibrant coloration and slightly elongated fins compared to females. A distinctive morphological feature is the wedge-shaped dark mark located on the caudal region, complemented by subtle coppery-garnet hues on the upper body, which contribute to its striking appearance. The fins are generally transparent with a hint of coloration, and the species possesses a well-defined lateral line, aiding in hydrodynamic sensing. Defensive adaptations include a schooling behavior that provides safety in numbers, as well as a streamlined body shape that allows for quick evasive maneuvers.
Behavior & temperament
Pretty Tetras are social fish that thrive in groups, exhibiting a strong tendency to form schools, which is essential for their well-being and stress reduction. They primarily inhabit the mid to upper water column, displaying a peaceful temperament with low aggression levels, making them ideal for community tanks. Breeding behavior is characterized by egg scattering, where females release eggs in open water, allowing males to fertilize them externally. In their natural habitat, they are often found in slow-moving streams and rivers, where they exhibit a dynamic swimming style, darting among aquatic vegetation and submerged structures.
Diet & feeding
In the wild, Pretty 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.
