Probarbus labeamajor · Freshwater Fish

What Thicklip Barb look like
Probarbus labeamajor, commonly known as the Thicklip Barb, exhibits a robust, laterally compressed body that can reach an impressive maximum adult size of up to 36 inches (90 cm). This species is characterized by its notably thick, fleshy lips, which are a distinctive feature among barbs. The coloration is primarily silver with golden tones, providing a striking appearance in its natural habitat. Sexual dimorphism is subtle, with males typically displaying slightly more vibrant coloration during the breeding season, while females are generally larger and rounder due to egg development. The Thicklip Barb possesses a well-developed lateral line system, aiding in its sensory perception in turbid waters. Its dentition is adapted for an omnivorous diet, featuring pharyngeal teeth that assist in grinding food. Additionally, the species has a pronounced adipose fin, contributing to its streamlined shape, which is advantageous for swift movement in riverine environments.
Behavior & temperament
The Thicklip Barb is primarily a social fish, often found in large schools, which provides safety in numbers against predators. It typically occupies the mid to upper water column in riverine systems, demonstrating a pelagic lifestyle. Breeding behavior involves egg scattering, where females release eggs into the water column, allowing for external fertilization by males. This species exhibits a generally peaceful temperament, although it can display territoriality during breeding periods. The Thicklip Barb is known for its active swimming patterns, often engaging in foraging behaviors that involve sifting through substrate for food, making it a dynamic presence in its aquatic environment.
Diet & feeding
In the wild, the Thicklip Barb is an omnivore, feeding on a varied diet that includes plant matter, detritus, and small invertebrates. In captivity, it requires a balanced diet that includes high-quality pellets, frozen or live foods, and plant-based supplements to ensure optimal health and coloration.
