Five Banded Barb
Desmopuntius pentazona
A small, peaceful, and beautifully colored schooling cyprinid native to the blackwater peat swamps of Southeast Asia. Often confused with the much more aggressive Tiger Barb, the Five Banded Barb is entirely peaceful and will not nip fins. They are somewhat shy and require a well-planted tank with dim lighting or floating plants to feel secure and show their best reddish-orange colors.

Five Banded Barb Care Guide Summary
The Five Banded Barb, scientifically known as Desmopuntius pentazona, belongs to the Cyprinids family group. Adults reach a maximum size of approximately 5 cm and have a fusiform body shape with a moderate growth rate. Classified as peaceful, this species primarily occupies the mid-level and bottom zones of the aquarium and produces a low level of biological waste.
To thrive, the Five Banded Barb requires a freshwater only aquarium with a minimum volume of 60 litres and a tank length of at least 60 cm. Water temperature should be maintained between 22°C and 28°C, with a pH range of 4.5–7 and a general hardness of 1–10 dGH. A low water flow is preferred.
Due to its specialist needs, the Five Banded Barb is best suited for fishkeepers who can provide a carefully planned setup. The Five Banded Barb is typically available in one standard form.
Five Banded Barb Habitat Setup
When setting up an aquarium for the Five Banded Barb, a low water flow best suits their natural preferences. Because this species occupies the mid-level and bottom zones, the aquarium layout should prioritise open swimming space in the centre of the tank for free movement and sufficient floor space with hiding spots among rocks, wood, or dense planting. Useful additions include leaf litter or blackwater tannins to replicate their natural soft-water habitat, dense planting to provide cover, break sightlines, and reduce stress, and floating plants to diffuse overhead light and create shaded areas.
Five Banded Barb Compatibility Notes
Classified as peaceful, the Five Banded Barb is a schooling species that feels most secure in a sizeable group, where natural shoaling behaviour reduces stress and brings out their best colours. Selecting tankmates that favour different water layers from the mid-level and bottom zones can help reduce competition and territorial overlap.
Who Five Banded Barb Is Actually For
Five Banded Barb is best for a fishkeeper who wants a species that can settle into a calmer community setup and can provide a keeper who can commit to a proper group of at least 6. It makes the most sense for a hobbyist who will actually build around its needs, especially plants.
The most common mistake is buying Five Banded Barb for looks first and only later discovering how its adult size, behavior, or bioload changes the whole tank plan. Another frequent problem is underestimating its social needs. A token pair or trio often behaves very differently from a real group.

Fish Similar to Five Banded Barb
Tiger Barb
Puntigrus tetrazona
A highly active, schooling cyprinid famous for its striking black stripes and infamous reputation as a fin-nipper. They are boisterous and must be kept in larger groups (6+) to keep their pecking order internal. They should never be housed with slow-moving or long-finned tankmates like Bettas, Guppies, or Angelfish.
Cherry Barb
Puntius titteya
A peaceful, schooling cyprinid endemic to the shaded streams of Sri Lanka. Unlike many of its barb cousins, the Cherry Barb is not a fin-nipper and makes an excellent community fish. They thrive in heavily planted aquariums with subdued lighting and leaf litter. Males display a striking cherry-red color, especially during spawning.
Chinese Barb (Green Barb)
Puntius semifasciolatus
A hardy, active, and peaceful schooling cyprinid originally from the Red River basin in Asia. While the wild form is a metallic green/silver, a highly popular selectively bred yellow morph (the 'Gold Barb') dominates the aquarium trade. They are distinctly subtropical and thrive in unheated or cooler water setups.
Rhomb Barb
Desmopuntius rhomboocellatus
A striking, peaceful schooling fish from the peat swamps of Borneo. Known for the distinctive snake-skin or rhomboid markings on its flanks. Unlike the related Tiger Barb, it is completely peaceful and somewhat shy, requiring heavily planted tanks with tannin-stained (blackwater) conditions to feel secure and show its best reddish-orange colors.
Black Ruby Barb
Pethia nigrofasciata
An active, schooling cyprinid endemic to the shaded forest streams of Sri Lanka. They are peaceful but highly energetic, making excellent community fish for cooler tropical setups. Unlike the notorious Tiger Barb, Black Rubies are generally peaceful and rarely nip fins, provided they are kept in a proper shoal of at least 6. Their deep colors emerge best in heavily planted, slightly dim environments.
Melon Barb
Haludaria fasciata
An active, schooling cyprinid endemic to the flowing rivers of Southern India. They are named for the stunning red/pink 'melon' coloration males develop, which contrasts beautifully with their dark vertical bands. They are energetic swimmers that require plenty of open swimming space and must be kept in groups to curb potential fin-nipping behavior.
