Parancistrus aurantiacus (L031, Magnum Pleco) is a robust loricariid from the Ucayali, Tocantins and Xingu basins needing strong flow and clean water.

Overview

Taxonomy

  • Family: Loricariidae
  • Subfamily: Hypostominae
  • Genus: Parancistrus
  • Scientific name: Parancistrus aurantiacus
  • L-number: L031

Habitat

FishBase and Wikipedia report the species from the Ucayali, Tocantins and Xingu River basins in Brazil and Peru. These are warm, fast-flowing tropical drainages, and the fish needs strong water movement and clean, oxygenated conditions.

Tank requirements

  • Minimum tank volume: 400 L
  • Temperature: 24-28 °C (within the 22-27 °C wild range per FishBase)
  • pH: 6.0-7.5
  • GH: 2-12 °dGH
  • Lifespan: 8-12 years
  • Provide driftwood, caves and strong, well-oxygenated flow

Diet

Omnivorous. As a loricariid it grazes on aufwuchs and biofilm and accepts sinking prepared foods and vegetable matter in the aquarium.

Compatibility

A robust, mostly nocturnal bottom-dweller. It can be territorial toward other plecos, so it should be given ample space, caves and high flow.

Breeding

A cave-spawner; breeding is considered advanced and is rarely achieved in the aquarium.

Conservation status

IUCN Red List: Near Threatened (assessed 2020).
