Stingray Potamotrygon motoro

Native to the river basins of the Uruguay Paraná Orinoco, and Amazon, the Motoro or Ocellate river stingray (Potamotrygon motoro) is one of the most popular species amongst the home aquarist.


Although not recommended for the beginner, the Motoro is a great specimen species for the experienced keeper with a large aquarium. They do demand good water quality without the least trace of Ammonia or Nitrite, and their heavy diet necessitates a good filtration system, but this is no less than any other large fish deserves. Regular water changes are also essential, but given good conditions they are a hardy and long lived species, (15 - 20 years), which do breed successfully in captivity.

Stingrays are carnivorous, feeding on small clams, mussels and invertebrates that live in the sand and mud and have powerful teeth to crush open the shells. In the aquarium they happily accept Whitebait, cockles and even earthworms. On the down-side they do grow big, (60cm +) and need plenty of free swimming space.

Much is often made of their poison barb, located halfway along their tail, and certainly capable of inflicting a painful wound if used aggressively. However unless the aquarist is like to be wading in the aquarium, or is stupid enough to grab the ray by it's tail, they are extremely unlikely to ever see this defensive weapon raised in anger or in fear.
