Stingrays for Freshwater Aquariums
Freshwater stingrays require specialized aquarium setups well in advance of ordering. The Motoro, Hystrix, and Florida stingrays all require a large aquarium either with no substrate on the bottom or with fine sand on the bottom. Stingrays are carnivores, and they feed slowly so it is generally recommended to have only the stingray or a couple of stingrays of the same type in the aquarium. They will eat smaller fish they are housed with, and they may be injured by larger and more aggressive fish.
