Species-specific aquarium care
- Tank: At least 24 in long and 12 in front to back for one adult (adults commonly reach about 2.8 in / 7 cm).
- Water: Freshwater.
- Temperature: 68–79°F (range recorded for this species).
- pH: 6–8.
- Hardness: 5–19 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, 68–79 °F, pH 5–8, 1–20 dGH.
- Behaviour: temperament territorial; 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 well-decorated set-up.”
- Diet: “Probably an omnivore feeding primarily on aquatic invertebrates, as well as smaller amounts of plant material and organic detritus in nature.”
- Tankmates: “This species is notoriously aggressive with a reputation for biting the fins of other fishes, although this behaviour only seems to be pronounced when insufficient numbers are purchased or space is limited.”
- Breeding: “Like most small cyprinids Puntigrus spp.”

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.
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.
Climate & lighting
| Water | 68–78.8°F |
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.
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.
Health watch
- Ammonia toxicity.
- Nutritional deficiencies.
Understanding the animal
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 lives | Lives in freshwater. Uses both the bottom and open water. Feeds on worms, small crustaceans and plant matter. |
| Water it lives in | Freshwater, 68–79 °F (20–26 °C), pH 6–8, hardness 5–19 dH. |
| Climate | Tropical climate. |
| Behavior to plan for | Breeding: open water/substratum egg scatterers. |
What this means for care
- Keep water within its wild range, 68–79 °F.
Native climate (measured)
Native climate (measured)
| Warm-season highs | about 89°F (up to 91°F in the hottest sampled areas) |
| Cool-season lows | about 71°F (down to 65°F in the coldest sampled areas) |
| Average temperature | 77–81°F across sampled records |
| Relative humidity | 78–82% on average (driest month about 75%) |
| Rainfall | about 2449 mm a year, spread fairly evenly |
Measured at 33 wild occurrence records sampled against WorldClim 2.1 climate data (1970–2000 averages). Air conditions in the range are ecological context, not enclosure settings: microhabitats such as burrows, leaf litter or basking rocks can be cooler, warmer or more humid.

| Appearance and size | The tiger barb can grow to about 7-10 long and 3-4 wide, although they are often smaller when kept in captivity. Some can grow to around 13 centimeters as well. Native fish are silver to brownish yellow with four vertical black stripes and red fins and snout. — Wikipedia (community-edited) |
| Biology | Adults feed on worms, small crustaceans and plant matter. Migratory behaviour is undetermined. Aquarium keeping: in groups of 5 or more individuals; not to be kept with long-finned fishes; minimum aquarium size 60 cm. — FishBase |
