What Spanner Barb look like

The Spanner Barb (Barbodes lateristriga) exhibits a fusiform body shape, typically reaching a maximum adult size of 5-7 inches (12-18 cm). Its most distinctive feature is the dark T-shaped or spanner-shaped marking on the flanks, which consists of a vertical bar connected to a horizontal stripe, providing an immediate visual identification. The body is predominantly silver with a slight sheen, complemented by reddish fins that enhance its aesthetic appeal. Sexual dimorphism is subtle; males tend to exhibit more vibrant coloration during breeding, while females may appear fuller-bodied when gravid. Defensive adaptations include a laterally compressed body that allows for agile maneuvering in the water column, and the presence of a lateral line system that aids in detecting movement and vibrations in the surrounding environment.

Behavior & temperament

Spanner Barbs are generally social fish, often found in small to medium-sized schools, which provides them with safety in numbers. They inhabit the mid to upper levels of the water column, displaying pelagic behavior. During breeding, they exhibit egg-scattering behavior, where females release eggs over vegetation or substrate while males fertilize them externally. Their temperament is typically peaceful, although they can exhibit mild territoriality during breeding periods, making them suitable for community tanks with other non-aggressive species.

Diet & feeding

In the wild, Spanner Barbs are omnivorous, feeding on a varied diet that includes plant matter, small invertebrates, and detritus. In captivity, they thrive on a balanced diet of high-quality flake food, supplemented with live or frozen foods such as daphnia and brine shrimp, as well as vegetable matter to meet their nutritional needs.
