Freshwater Stingray (Potamotrygon motoro)

Potamotrygon motoro

The Motoro Stingray (Potamotrygon motoro) is the most widely available and commonly kept freshwater stingray species, prized for its striking "polka-dot" pattern of orange-gold ocelli against a dark olive-brown disc. Native to virtually every major South American river system, P. motoro is hardier and more adaptable than many of its rarer congeners, making it the ideal entry point for aquarists venturing into potamotrygonid keeping. However, "entry point" is relative — freshwater stingrays demand large, meticulously maintained aquaria, strict water quality discipline, and absolute respect for their venomous caudal spine. This The Fish Collection guide provides comprehensive husbandry instructions for one of the most rewarding and visually spectacular freshwater species in the hobby.
