From which specific South American river basin do the *Hypancistrus zebra* exclusively originate?

Answer

Xingu River basin

The natural habitat of the Zebra Pleco is extremely localized, defining their rarity and vulnerability in the wild. These fish are endemic solely to a specific geographic region within the Xingu River basin located in Brazil. This particular environment imposes strict requirements on captive care, as the native water is fast-flowing, highly oxygenated, and possesses specific thermal and chemical profiles dictated by the river's characteristics.
