Denisons Barb (Roseline Shark)

Denisons Barb (Roseline Shark) requires a minimum of 55 gallons for healthy adults. The minimum is based on the species' adult size (6 inches), territorial range, and behavior pattern. Most Denisons Barb (Roseline Shark) sold at small juvenile size will reach full adult size within 12-24 months and the system must be sized to the adult, not the juvenile.

The Denisons Barb is rated intermediate difficulty on this care sheet. It needs a tank of at least 55 gallons, a temperature of 74-80°F and pH 6.5-7.5. Adults reach about 6 inches and live 5-8 years. Denisons Barb (Roseline Shark) is a intermediate-care freshwater species that thrives in tanks of 55 gallons or larger with stable parameters.

Denisons Barb (Roseline Shark) prefers freshwater parameters: Temperature: 74-80°F pH: 6.5-7.5 GH: 4-12 dGH KH: 3-8 dKH Ammonia + nitrite: Both 0 ppm Nitrate: Under 20 ppm long-term Copper: 0 (especially critical for invertebrates) Use dechlorinator on every water change. Test parameters weekly during cycling, biweekly once stable. Stable consistency beats sliding-scale "ideal" parameters.

Denisons Barb (Roseline Shark) is a omnivore. Eats a varied diet of pellets, frozen foods, and supplemental greens.

Denisons Barb (Roseline Shark) (Sahyadria denisonii) is native to specific tropical and subtropical freshwater systems. The captive-bred Denisons Barb (Roseline Shark) sold at most LFS comes from generations of farmed stock and is generally hardier and better-acclimated to tank conditions than wild-caught equivalents. Wild specimens are occasionally available for keepers chasing original-bloodline coloration or biotope-accurate stocking.
