Active, shoaling Longfin Barb with silver-green body, dark flank markings and orange-red fins. Best in a spacious, well-filtered group setup with robust tank mates.
Adult size is the maximum length this species reaches at full maturity (scientific sources). The livestock you receive will be younger and smaller — pick a size variant above for the actual shipping size. Photos are AI-enhanced, so the animal may show subtle colour or marking differences.

Longfin Barb (Dawkinsia arulius) is an active, elegant schooling barb for aquarists who want movement, colour and natural group behaviour in a larger community aquarium. This product covers the current Shopify size options, 3.5-4.5 cm and 5-7 cm, so you can choose smaller growers or a more developed group while keeping the same species page and care information.
The old names Puntius arulius and Barbus arulius still appear in supplier lists and hobby searches, but the accepted name used here is Dawkinsia arulius. The fish is also known as the Arulius Barb or Aruli Barb. Because these trade names have sometimes been used for closely related Dawkinsia barbs, compare the stock by the exact source photo, size option and care notes on this page rather than by trade name alone.
The exact Petra source photo shows the classic longfin barb shape: a deep, streamlined silver-green body, bold dark flank blotches, a long dorsal extension and orange-red colour through the tail and fins. Good specimens look alert and balanced, with clear eyes, clean scale edges and no collapsed or clamped fins. Males usually develop stronger colour and more impressive dorsal-fin extension as they mature, while females are often fuller-bodied.
Juveniles may look paler than fully settled adults. That is normal for active barbs after transport or while still growing. In a well-maintained shoal, with clean water and a varied diet, the metallic green sheen and warm fin colour become much more obvious.
Dawkinsia arulius is an Indian cyprinid associated with the Cauvery basin and larger, well-oxygenated streams, rivers and lakes. FishBase records the species as freshwater, schooling and omnivorous, with spawning activity near the surface. GBIF and FishBase both retain the accepted Dawkinsia arulius name while listing older combinations such as Puntius arulius and Barbus arulius as synonyms.
For aquarium care, the important point is habitat style: clean water, good oxygen, open swimming space and enough current to keep the fish active without blasting them around the tank. This is not a slow, still-water nano fish. It belongs in a roomy aquarium built around a confident shoal.
Plan for a group, not a single display fish. A minimum of six Longfin Barbs is the practical starting point, and more are better when tank space allows. A 180 litre aquarium with a long swimming run gives the group room to move, display and settle. For a mature shoal, especially with the larger 5-7 cm option, a 120 cm tank length is the safer long-term target.
Use strong biological filtration, regular water changes and visible surface movement. A river-style layout works well: fine gravel or sand, smooth stones, wood, open central swimming room and planted edges. Robust plants such as Java fern, Anubias and Vallisneria are better choices than soft, delicate stems because active barbs may browse tender leaves. Keep the lid secure, as fast barbs can jump when startled.
Longfin Barbs are straightforward omnivores, but they look and behave best on variety. Use a quality flake or small pellet as the staple, then rotate frozen or live foods such as bloodworm, daphnia, mosquito larvae and Artemia. Spirulina flakes, vegetable-based granules or small amounts of blanched greens help round out the diet.
Feed small portions once or twice daily. They are fast feeders, so watch that quieter tank mates are still getting food. A varied diet supports fin condition, breeding colour and the confident shoaling behaviour that makes this species worth keeping.
This is a peaceful barb in the right setup, but it is not gentle in the way a small rasbora is gentle. The Longfin Barb is quick, social and sometimes pushy at feeding time. Kept singly or in a tiny group, it can become nervous or nippy. Kept in a proper shoal, most of that energy stays within the group and the fish look far more natural.
Choose robust, active tank mates of similar size: other medium barbs, danios, rainbowfish, larger rasboras, peaceful loaches and confident bottom dwellers. Avoid slow fancy fish with trailing fins, very small tetras, tiny rasboras, dwarf shrimp and shy species that dislike busy movement. The aim is a lively community where every fish can compete calmly and use the space well.
Like many barbs, Dawkinsia arulius is an egg-scattering cyprinid. FishBase notes surface-associated spawning, and in aquaria the safest method is a separate breeding tank with fine-leaved plants, spawning mops or mesh that lets eggs fall away from the adults. Condition the adults with rich frozen and live foods, then remove them after spawning because eggs and fry may be eaten.
Most keepers buy this species for movement and display rather than breeding, but understanding the breeding style helps explain the setup: clean oxygenated water, plant cover, open swimming room and a confident group are all part of making the fish behave naturally.
