Nautilus Marine Wholesale now has wild Colombian stingrays in stock. The company was able to get both the marble motoros Potamotrygon motoro and ‘yellow hystrix’ (trade name) Potamotrygon orbignyi. According to Nautilus, “wild rays have been extremely difficult to import since they were listed as CITES Appendix III species in January. This is the first time we have been able to import these species since their listing. A CITES III listing is not an indication that they are endangered or threatened, it is a category used to track numbers in international trade.” The company’s Colombian supplier was able to come up with CITES permits to get the stingrays.
The marble motoros have the nice spotted/marbled pattern around the edge of the disc. All of the rays should only go into fully cycled tanks–they have no tolerance for ammonia or nitrite—and either a bare-bottom tank or a smooth sand. Nautilus uses sand initially on the imports because they’re not used to bare-bottom tanks, but will transition to bare bottom once they settle in.
