Aracu-flamengo
The aracu-flamengo is a native Amazonian characin that turns up on hooks throughout the Amazon Basin — often as a surprise catch when anglers are after bigger quarry, but also deliberately targeted by local subsistence and sport fishers.
Its bold yellow-and-black banding makes it one of the most visually striking fish you'll pull from Amazonian waters, and it's a legitimate table fish in riverside communities.
Scientific Name: Leporinus fasciatus
Also known as Aracu flamengo, Aracu amarelo, Aracu pinima, Piau flamengo, Leporinus listado, Ferreirinha, Banded leporinus
- Bright yellow or beige body crossed by 8–12 bold vertical black bands; orange tints often appear on the head and tail fin, making it unmistakable in hand.
- Torpedo-shaped body typical of the Anostomidae family; the slightly downturned snout and visible teeth distinguish it from similar-sized characins.
- Typical catches run 15–25 cm; the species can reach 30 cm (roughly 12 inches), with adult females generally growing larger than males.
What to know
Habitat Distribution
- Native to the Amazon Basin; found throughout the river system and its major tributaries across Amazonas, Pará, Mato Grosso, and surrounding states.
- Prefers fast-moving water — main-channel runs, rocky rapids, and the edges of flooded forest during high water.
- Also moves into flooded várzea and igapó forests during the high-water season, foraging among submerged roots and vegetation.
Key Locations
- Rio Negro basin (Amazonas state) — rocky runs and flooded forest throughout this massive blackwater system hold aracu-flamengo year-round.
- Sucunduri River (Amazonas) — a large tributary system with varied habitat where the species appears alongside peacock bass and other Amazonian targets.
- Aracá, Cuiuni, and Demeni rivers (Amazonas) — upper Rio Negro tributaries with fast, clear water and rocky structure well-suited to this species.
- Madeira River basin (Rondônia/Amazonas) — whitewater tributaries like the Machado River support healthy populations in fast-flowing reaches.
Specific Spots
- Rocky rapids and fast-water chutes concentrate aracu-flamengo; they hold in the current seam just behind boulders where food washes through.
- Submerged root tangles and fallen timber along flooded forest edges during high water — the fish use this structure for cover and feeding.
- Shallow gravel and sand bars at tributary mouths, where current slows and food collects, draw feeding fish, especially in the dry season.
Aracu-flamengo FAQ
Answers from onWater's species guide.
What are the best lures and bait for Aracu-flamengo?
Natural baits, earthworms, small pieces of fruit, and dough or masa-style baits, are the go-to for local anglers and consistently produce across the Amazon Basin. Small spinners (sizes 0–2) and tiny jigs in natural colors work in faster water, where the fish are actively chasing food through the current.
When is the best time to fish for Aracu-flamengo?
Dry season (roughly July–November) concentrates fish in main channels, rocky runs, and tributary mouths, generally the most productive time for targeted fishing.
How do you catch Aracu-flamengo?
Local anglers in the Amazon typically fish aracu-flamengo from the bank or small skiffs using light spinning gear and natural baits, working rocky rapids and current seams.
What do Aracu-flamengo eat?
Omnivorous and opportunistic across seasons: eats aquatic plants, algae, fallen fruits, worms, and small invertebrates. Small natural baits, worms, pieces of fruit, or dough baits, consistently produce.
Where do Aracu-flamengo live?
Native to the Amazon Basin; found throughout the river system and its major tributaries across Amazonas, Pará, Mato Grosso, and surrounding states. Prefers fast-moving water, main-channel runs, rocky rapids, and the edges of flooded forest during high water.
