Denisons Barb (Roseline Shark)

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.

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.

For a Denisons Barb (Roseline Shark) setup: tank sized for the adult footprint, HOB or canister filter rated 4-6x tank volume, dechlorinated water, appropriate temperature heater, and stocking-appropriate hardscape and plants.

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. Quality flake or pellet (Hikari, New Life Spectrum, Tetra) plus frozen mysis or bloodworms 2-3x weekly produces best color and behavior. Feed Denisons Barb (Roseline Shark) appropriately for its size + activity level. Overfeeding is the #1 cause of water-quality crashes in tanks of all sizes.

Denisons Barb (Roseline Shark) works in community tanks with peaceful species in similar size class. Adult-size matters more than purchase-size when planning stocking. Avoid mixing aggressive with passive species.
