Colombian Tetra Care Guide
Hyphessobrycon columbianus · Freshwater Fish
What Colombian Tetra look like
Hyphessobrycon columbianus, commonly known as the Colombian Tetra, exhibits a robust and laterally compressed body shape, reaching a maximum adult size of approximately 2.5 to 3 inches (6 to 7.5 cm). This species displays sexual dimorphism, with males typically being slightly smaller and exhibiting more vibrant coloration compared to females. The Colombian Tetra is characterized by its striking coloration, featuring a brilliant metallic blue to silver upper body that transitions to a vivid blood-red hue on the lower fins and tail, creating a stark contrast. Notable morphological features include a well-defined lateral line, which aids in hydrodynamic sensing, and a small adipose fin situated between the dorsal fin and the caudal fin. The dentition is composed of small, fine teeth adapted for grazing on algae and small invertebrates, while the finnage is well-developed, with a triangular dorsal fin and forked caudal fin that enhance its swimming agility.
Behavior & temperament
Colombian Tetras are typically found in small to medium-sized schools, exhibiting a social hierarchy where dominant individuals may assert themselves through displays of color and posture. They are primarily pelagic, inhabiting the mid to upper water column in their natural habitat, where they engage in active swimming and foraging behaviors. During breeding, they are egg scatterers, releasing adhesive eggs among aquatic vegetation, which provides cover for the developing fry. Their temperament is generally peaceful, making them suitable for community tanks, although they can exhibit mild territoriality during breeding periods.
Diet & feeding
In the wild, Colombian Tetras are omnivorous, feeding on a varied diet that includes small invertebrates, plant matter, and detritus. In captivity, they thrive on a balanced diet of high-quality flake food, supplemented with live or frozen foods such as brine shrimp and daphnia, as well as vegetable matter to ensure optimal health.
