Narayan barb (Pethia narayani)

Fairly easy — among the hardier Pethia. Tolerant, gentle, unfussy about food, happy at routine 22–26 °C in soft, slightly acidic water of pH 6.0–7.0. Note that at 5.8–8.6 cm it's no miniature: plan 80 L+, and treat schooling as its foundation of condition — six minimum, eight or more ideally.

Six minimum, eight to ten ideally. Like all Indian Pethia, its security is collective: sufficient numbers bring full color and confident movement; too few mean permanent corner-sulking and dullness. The school is also the main display — a shoal of adults glowing gold-pink under soft light is premium community-tank material.

Omnivore with a herbivorous tilt: quality micro-pellets and flakes as staple, algae wafers and blanched greens (spinach, peas) regularly, frozen bloodworms occasionally for protein. Its small gape needs fine granules; plant matter matters for both color and gut health — all-meat diets cause constipation and fading.

Essentially no. It's a safe community citizen mixing with tetras, corydoras, small plecos, and gentle dwarf cichlids. Playful chasing of non-conspecifics happens but rarely harms. The real risk runs the other way: its modest size and feeding competitiveness mean aggressive fish can starve it out.

Three usual causes: school too small (jump to eight and watch it improve), diet lacking carotenoids (add astaxanthin-rich food or bloodworms), lighting too cool-white (warm or full-spectrum brings out the gold-pink). Also note new fish are dull for two weeks of acclimation — don't rush adjustments.

Hard at home but not impossible. Like the cherry barb: soft water (GH under 5), slightly acidic (pH 6.0–6.5), 26–28 °C, eggs scattered in dense plants, parents separated to prevent egg-eating. Eggs hatch in 24 hours; fry need infusoria. The catch: most domestic stock is imported adults, and conditioning pairs to spawn proves difficult.

Same genus, different species: the cherry barb (Pethia titteya) is wine-red and famous; Narayan's barb is gold-pink with dusky lateral markings and slightly larger. They mix perfectly with identical water needs. Choose cherry for the classic, Narayani for the niche-premium look — the reason it's rising in the hobby.

89 L is the profile floor; 80–120 L is the practical zone. It swims actively and schools hard — cramped tanks under 60 L crowd the group and swing water quality. A planted tank with soft light, dense vegetation, and gentle flow suits both its native Western Ghats streams and its display value.

Water first (ammonia and nitrite — the leading cause of single community-fish deaths), then purchase timing: import-shipping stress often kills one to two weeks after arrival. If parameters test clean and everyone else is fine, treat it as an individual event with a quarter water change. Prevention: quarantine new imports for a week — standard procedure.

pH 6.0–7.0, GH 5–15, 22–26 °C, soft-acid preferred. Despite being Indian, it adapts across a fair range — the real key is stability: change water within 2 °C, avoid pH swings. Consistent weekly quarter-changes beat chasing perfect numbers — the universal truth of community keeping.
