Roseline Shark (Denison Barb)
The Roseline Shark, scientifically known as the Denison Barb, is a striking freshwater species distinguished by its sleek body, bold red lateral stripe, and contrasting black and white markings on the head and tail. Despite their "shark" common name, these are peaceful, active barbs that thrive in well-oxygenated aquariums with strong water flow and plenty of open swimming space. They're schooling fish that perform optimally in groups of six or more, displaying natural behaviors and vibrant coloration when kept together. Maintain water temperatures between 72-79°F with a pH of 6.0-7.0 in a mature, efficiently-filtered system. Feed a balanced diet of quality pellets, flakes, and occasional live foods to support their energetic nature and maintain their brilliant red striping. These fish appreciate moderate plant coverage and open areas for active swimming. Hardy and visually captivating, Roseline Sharks are excellent for intermediate to advanced aquarists seeking an engaging, colorful schooling species with dynamic movement and minimal aggression toward compatible tankmates.
