Care at a glance

Species-specific aquarium care

  • Tank: At least 24 in long and 12 in front to back for one adult (adults commonly reach about 4.9 in / 12.52 cm).
  • Water: Freshwater (tolerates brackish).
  • Temperature: 57–72°F (range recorded for this species).
  • pH: 6.5–7.
  • Hardness: 0–10 dGH.
  • Layout: Uses both the bottom and open water: give open swimming space plus cover near the substrate.
  • Diet: Eats a varied diet: mix quality prepared foods with frozen and live foods. FishBase classes it as a omnivore.

Calculated from this species' own FishBase record: tank size from its typical adult length and swimming zone, water values from its recorded ranges. The group guide below fills in general care.

Care guide

Species care notes

  • Tank: a base of at least 31 × 12 in (roughly 19 US gallons); space needed is rated “modest tank”.
  • Water: a fairly wide range, from slightly acidic to slightly alkaline, 64–77 °F, pH 6–7.5, 2–12 dGH.
  • Behaviour: temperament peaceful; a shoaling fish best kept in a group of six or more; suited to a community tank.
  • Difficulty: Easy (Seriously Fish rating).

Short excerpts from the species profile:

  • Setup: “Choice of décor is not especially critical though it tends to show better colouration in a heavily-planted set-up with a dark substrate.”
  • Diet: “Likely to be a foraging omnivore feeding on worms, insects and other small invertebrates, as well as plant material and organic detritus.”
  • Tankmates: “Generally very peaceful making it an ideal resident of the well-researched community aquarium.”
  • Breeding: “Like most small cyprinids Pethia spp.”

Group care guide

Carps and barbs

Applies to most species in this group. Habitat: The listed barbs and freshwater sharks occupy Asian streams, rivers and floodplain waters, with bala sharks also using natural lakes. Individual species can differ, so compare with the species numbers above and the linked sources.

Level 3 is an editorial rating reflecting large and territorial species. Temperature applies to tiger barbs and red-tailed black sharks; bala sharks are sourced at 68–82.4°F. Bala sharks reach about 35 cm and need very large quarters. Epalzeorhynchos are not managed like shoaling barbs. Tinfoil and Denison barbs, gold barbs and rainbow sharks require species-specific adult-size and water assessments; the tiger-barb minimum is not a family minimum.

Housing & setup

  • Tiger barbs need a base at least 80 × 30 cm (about 31 × 12 inches), with vegetation and driftwood cover.
  • Adult bala shark groups need a base at least 240 × 60 cm (about 96 × 24 inches), ample open swimming space and a heavy, tight lid.
  • Red-tailed black sharks need a base at least 120 × 45 cm (about 48 × 18 inches), with rocky refuges.
  • Use efficient filtration, water movement and high oxygenation for riverine bala and red-tailed sharks.

Diet

  • Quality flakes or granules containing plant material.
  • Live or frozen Daphnia, Artemia and bloodworms.
  • For larger bala sharks: chopped earthworms, prawns or mussels.
  • For bala sharks: shelled peas, blanched courgette or spinach.

Sources 922923924925

Social life

  • Keep tiger barbs in at least 8–10 and bala sharks in at least five. Avoid timid or long-finned companions for tiger barbs. Red-tailed black sharks become territorial toward similar-looking fishes.

Understanding the animal

About this animal

About this animal

It is a native of the upper Mekong, Salwen, Irrawaddy, Meklong and upper Charo Phraya basins in the countries of Nepal, India, Pakistan, Myanmar, Bangladesh, Thailand, and Sri Lanka. It has frequently been confused with the Odessa barb in the aquarium trade, but in that species the male is reddish-orange (lacking in P. ticto).

In the wild

In the wild

From this species’ own FishBase record (habitat, bottom type, water and breeding data), not its family. Good care copies these conditions.1

Where it livesLives in freshwater and brackish water, in rivers and streams, lakes, rice paddies. Uses both the bottom and open water. Found in still, shallow, marginal waters of tanks and rivers, mostly with muddy bottoms. They browse close to the substrate in shallow water. Feed on crustaceans, insects and plankton. About 150 eggs are laid in batches of about 20 at a time; eggs hatch in about a day, and fry are free-swimming the next day. Aquarium keeping: in groups of 5 or more individuals; minimum aquarium size 60 cm.
Water it lives inFreshwater / brackish water, 57–72 °F (14–22 °C), pH 6.5–7, hardness 10 dH.
ClimateSubtropical climate.
Wild dietTroph of juv./adults from 1 study.
Behavior to plan forBreeding: open water/substratum egg scatterers.

What this means for care

  • Keep water within its wild range, 57–72 °F.
  • It tolerates or needs brackish water; check salinity needs before setup.
