Tiger barbs are bright, bold and full of energy. With their golden bodies, four black bands and red-tipped fins, they bring constant movement to a tank. They also have a reputation as fin nippers, and that reputation is earned when they are kept the wrong way. Kept properly, in a decent-sized group with the right companions, tiger barbs are hardy, entertaining and easy to look after. This guide covers how to get it right.

Where Tiger Barbs Come From
Tiger barbs come from Sumatra and Borneo in Southeast Asia, where they live in clear to slightly tannin-stained streams with plenty of plants and some current. Today almost all tiger barbs in the trade are captive bred, and they are among the hardiest community fish available, coping well with a wide range of water conditions.
Colour Varieties
Alongside the classic striped form, you will see several selectively bred varieties. The green or moss tiger barb has a dark green, almost black body. Albino tiger barbs are pale with faint bands and red eyes. All share the same care needs and temperament, and they will shoal together.
The Fin Nipping Question
Tiger barbs nip fins, but mostly because of how they are kept. In small groups, they turn their natural boisterous energy on other fish. In a larger group, they chase and squabble among themselves, which keeps their attention away from tank mates.
The rules are simple:
- Keep at least six, and ideally eight to ten or more. This is the single biggest factor.
- Avoid slow fish with long fins. Bettas, angelfish, fancy guppies and gouramis with trailing fins are likely targets.
- Give them space. A cramped tank makes nipping worse.
- Add plants and decor. Breaking up lines of sight reduces chasing.
Tank Size and Setup
Tiger barbs are fast, active swimmers. A tank of 80 to 100 litres and at least 90 cm long suits a group of eight. Bigger groups, and larger tanks, give a better display and calmer fish.
- Open swimming space. Keep the front and middle of the tank clear.
- Planted edges. Dense planting along the back and sides gives cover. Hardy plants such as java fern, anubias and vallisneria cope well, although tiger barbs may nibble soft leaves.
- Moderate flow. They enjoy some current; a filter rated for the tank with a moderate outflow suits them.
- Substrate. Sand or fine gravel. A darker substrate shows off their colours.
- A lid. Active barbs can jump.
Water Parameters
- Temperature: 22 to 26°C.
- pH: 6.0 to 7.8. Most UK tap water is fine.
- Hardness: Soft to moderately hard.
- Ammonia and nitrite: Always zero.
- Nitrate: Below 20 to 40 ppm, with weekly water changes of 20 to 30 percent.
Tiger barbs are hardy, but they still need a fully cycled tank. Add them once ammonia and nitrite have read zero for at least a week.
Behaviour
Expect constant activity. Tiger barbs chase one another, spar with flared fins and establish a pecking order within the group. This looks rough but is normal, and it is a sign the group is large enough. They spend most of their time in the middle of the tank and are usually first to the surface at feeding time.
Best Tank Mates for Tiger Barbs
Choose fish that are quick, robust and short-finned:
- Other barbs, such as cherry barbs and gold barbs
- Zebra danios and other active danios
- Larger tetras, such as black widow and serpae tetras
- Corydoras and bristlenose plecos on the bottom
- Clown loaches and yoyo loaches in larger tanks
- Rainbow sharks and red fin sharks in tanks with enough space

What to Feed Tiger Barbs
Tiger barbs are unfussy omnivores with big appetites:
- Staple: quality flake or small pellets.
- Frozen and live foods: bloodworm, brine shrimp and daphnia a few times a week.
- Vegetable matter: spirulina flakes or blanched peas and spinach for fibre.
Feed small amounts once or twice a day, only what they will clear in two to three minutes. They are greedy and will always look hungry, so resist the urge to overfeed. Browse our aquarium fish food for suitable staples and treats.
Males and Females
Males are slimmer, with brighter red on the snout and fins, and become more intensely coloured when displaying. Females are larger and rounder, especially when carrying eggs, with slightly duller colouring.
Breeding Tiger Barbs
Tiger barbs are egg scatterers and are one of the easier barbs to breed:
- Set up a separate tank of 40 litres or more at 25 to 26°C, with soft, slightly acidic water.
- Add fine-leaved plants, java moss or a spawning mop, or cover the bottom with mesh so eggs fall out of reach.
- Condition a pair or a small group with frozen and live foods for one to two weeks.
- Spawning usually happens at dawn. A female can scatter several hundred eggs.
- Remove the adults immediately afterwards, as they will eat the eggs.
- Eggs hatch in about 36 hours. Feed the fry infusoria at first, then baby brine shrimp and crushed flake.
Common Health Problems
Tiger barbs are tough, but they are not immune to illness. Watch for white spot after temperature drops or new arrivals, and fin rot where water quality slips. Most problems come back to water quality, so regular testing and water changes prevent the majority of issues. Quarantine new fish for two to four weeks if you can.
Buying Tiger Barbs
Look for active fish with sharp black bands, bright red fins and no white spots or torn fins. Buy a full group at once so they establish their hierarchy together. Our tiger barbs are delivered by tracked courier in insulated packaging; acclimatise them slowly and keep the lights low for the first day.
Frequently Asked Questions
How many tiger barbs should I keep?
At least six, ideally eight to ten or more. Larger groups nip less.
Are tiger barbs aggressive?
They are semi-aggressive. They chase and nip, mainly within their own group, and will nip slow, long-finned fish if kept in small numbers.
Can tiger barbs live with bettas?
No. A betta’s long fins make it a target.
Can tiger barbs live with guppies?
It is not recommended. Male guppies’ trailing tails are likely to be nipped.
Are tiger barbs good for beginners?
Yes, as long as you keep a proper group and choose tank mates carefully. They are hardy and forgiving of beginner mistakes.
