Barbs

Barbs are the restless, barb-bodied cyprinids of the Old World — quick, schooling river and stream fishes that span four continents. The aquarium core sits in tropical Asia: the tiger barb (Puntigrus), the rosy and odessa barbs (Pethia), the threadlike filament barbs (Dawkinsia), the brilliant denison or roseline “shark” (Sahyadria) of the Western Ghats, and the big silvery tinfoil (Barbonymus) — most of them split out of the old catch-all Puntius only after 2012. Beyond the trade, the family runs from the hundreds of small, plain African barbs (Enteromius) and the South African redfins to the powerful mahseers (Tor), the African yellowfish (Labeobarbus), and the temperate barbels of Europe, the Mediterranean and the Middle East. This section is built to the same standard as the cichlid, cory and pleco pages: researched, cited accounts with no Wikipedia and no invented facts.

The name “barb” is a hobby grouping, not a single lineage — and its taxonomy has been rewritten in living memory. The genus Puntius, which once held almost every small Asian barb, was broken apart by Pethiyagoda and colleagues in 2012 into Pethia, Dawkinsia, Haludaria, Puntigrus and a much-restricted Puntius, with Sahyadria erected for the roseline barbs soon after. We follow the Catalog of Fishes for valid names, so a fish you may know as Puntius often appears here under its current genus, with the older combination noted. The one thing nearly all barbs share is how they breed: they are egg-scattering, non-guarding fishes that release adhesive eggs over plants or gravel and tend neither eggs nor fry — so you will not find bubble-nests or mouthbrooding here.

Most barbs are social shoalers — kept in numbers they school tightly and squabble within the group rather than harassing tankmates; kept in twos and threes they turn into fin-nippers.

The denison or roseline barb of the Western Ghats is a hobby star and a cautionary tale: wild collection for the trade pushed it onto the IUCN Red List before captive breeding caught up.

Colour is a spawning signal: male rosy, odessa and many Pethia barbs flush red as they drive females through fine-leaved plants, scattering eggs the adults will eat if given the chance.

877 species in the atlas

We treat “barbs” as the barb-bodied cyprinids — grouped here by a friendly region-and-size axis (Asian barbs, Indian & Sri Lankan barbs, African barbs, big barbs & mahseer, and the European & western barbels) rather than by raw genus. The danios, rasboras, loaches, Garra and algae-eater “sharks” are deliberately left out — they belong to their own groupings. Following the Catalog of Fishes and FishBase, the valid set is large and the African and Eurasian tails are still being written up; new accounts are added as they are researched.

Species

877 of 877 species

Asian barbs · 184

The Southeast and East Asian barbs — the tiger (Puntigrus), clown (Barbodes), tinfoil (Barbonymus), checkerboard and many small schooling barbs of the lowland rivers, swamps and rice paddies of Indochina and Sundaland. The heart of the aquarium trade.

Indian & Sri Lankan barbs · 114

The barbs of the Indian subcontinent and Sri Lanka — the rosy and ticto barbs (Pethia), the filament barbs (Dawkinsia), the denison or roseline 'shark' (Sahyadria) and the melon barb (Haludaria). Many are Western Ghats and wet-zone endemics under pressure from collection and habitat loss.

African barbs · 255

The small African barbs — the vast Enteromius radiation across the continent's rivers and the South African redfins (Pseudobarbus). Mostly small, plain, little-known fishes of savanna streams, headwaters and seasonal floodplains; few ever enter the trade.

Big barbs & mahseer · 205

The giants of the family — the African yellowfish (Labeobarbus), the Asian mahseers (Tor, Neolissochilus), the giant barb (Catlocarpio) and the large Indian barbs. Powerful river fish, many prized as sportfish or food and several severely overfished.

European & western barbs · 119

The barbels of Europe, the Mediterranean, North Africa and the Middle East — Barbus, Luciobarbus, Capoeta and kin. Bottom-oriented, often migratory river fish of cooler, temperate waters — the original 'barbels' from which the whole group takes its name.
