Leporinus multimaculatus

A small headstander tucked into the narrow, shaded tributaries of Brazil's Amazonian shield river systems, Leporinus multimaculatus tops out around 4. 4 inches and grazes plant matter in a characteristic snout-down posture.
Its range spans the Araguaia, Tocantins, Xingu, and Jari drainages, plus coastal streams of Amapá state. No angling tradition surrounds it — this is a species that belongs to the aquarist and the field biologist.
Scientific Name: Leporinus multimaculatus
- One dark midline blotch on the front half of the flank, surrounded by five to seven additional dark blotches — the key marking that separates it from similar Leporinus species.
- Three teeth on the premaxilla and a subinferior (slightly downward-angled) mouth; close relatives typically carry four premaxillary teeth, making tooth count a reliable ID point.
- Twelve scale rows around the caudal peduncle; maximum size around 4.4 inches standard length, placing it among the smaller members of the genus.
What to know
Habitat Distribution
- Restricted to Brazil: small tributaries of the Araguaia, Tocantins, and Xingu river basins, the Jari basin, and coastal drainages of Amapá state — not found outside this range.
- A small-tributary specialist; narrow, shaded side channels are its core habitat rather than the main stems of large Amazonian rivers.
- Benthopelagic in habit — moves through the water column near the bottom in the low-gradient stream environments it favors.
Specific Spots
- Algae-covered substrate, submerged leaf litter, and patches of aquatic vegetation draw this species in — it grazes these surfaces in its characteristic head-down angle.
- Slower tributary margins and side channels hold more fish than fast main-channel flow; the calmer water suits both its feeding style and small body size.
