Five-banded barb
Desmopuntius pentazona
intermediate careOverview
The five-banded barb (Desmopuntius pentazona) is a peaceful, striking barb marked with bold vertical black bands over a warm orange-gold body. It looks superficially like a tiger barb but behaves nothing like one — it is gentle, somewhat shy, and needs soft, warm, acidic water. In a mature, planted, blackwater-style tank a shoal is calm, colourful and quietly beautiful.
Tank & water
A shoal is comfortable in 75 litres (20 gallons) or more with dense cover. Key requirements:
- Temperature: they like it warm, 24–28 °C, held steady with a heater.
- Soft, acidic water: target pH 5.5–7.0 and low hardness; botanicals and driftwood that tint the water suit them.
- Gentle filtration: a filter with soft flow matches their calm forest-stream origins.
- Shade and cover: dense plants, wood and dim light bring out their colour and confidence.
Feeding
Five-banded barbs are omnivores with modest appetites. Feed a quality flake or micro-pellet staple with frequent frozen or live foods — daphnia, bloodworm, brine shrimp — to draw out colour. Feed small amounts once or twice a day; shy individuals may feed better once the tank lights dim. In a mature blackwater tank they also graze on biofilm and tiny invertebrates among the leaf litter, so botanicals help support them between feeds and encourage natural foraging.
Tankmates
Match their calm nature with peaceful, soft-water species: harlequin rasboras, ember tetras, glowlight tetras, peaceful corydoras and small gouramis. Avoid boisterous or nippy fish that intimidate them. Keep a shoal of six or more — see best fish for a planted tank.
Common mistakes to avoid
- Hard, alkaline water (they need soft and acidic)
- Bright, bare tanks that leave them pale and shy
- Keeping too few, which increases stress
- Boisterous tankmates that outcompete them
Give five-banded barbs a warm, soft, planted blackwater tank and a proper shoal, and their bold bands and peaceful manners make them a connoisseur’s barb.
Five-banded barb — frequently asked questions
Is the five-banded barb the same as a tiger barb?
No. Despite the stripes, the five-banded barb (Desmopuntius pentazona) is peaceful and rather shy, quite unlike the nippy tiger barb. It needs softer, warmer, more acidic water and calmer tankmates.
Why does my five-banded barb look pale?
They fade when stressed, kept in too small a group, or in bright, bare tanks. Soft acidic water, a dark substrate, dense planting, dim light and a shoal of six-plus bring back their rich colour and confidence.
Are five-banded barbs hard to keep?
They are a step up from the toughest barbs because they prefer soft, warm, acidic water and can be shy. In a mature, planted, blackwater-style tank with a proper shoal, though, they are peaceful and rewarding.
