What To Know Before Buying Freshwater Stingrays for Sale

Stingrays are a class of rays that are closely related to sharks. Most types of stingrays are marine animals. However, there are a few species of freshwater stingrays that mostly live in the Amazon basin and other parts of South America.

Some kinds of freshwater stingrays are kept as pets in aquarium alongside other types of freshwater aquarium fish. They can be bought in-store or through online fish stores. Here’s what to know before you buy freshwater stingrays for sale.

An interesting fact about stingrays is that they actually have one or more barbed stingers at the end of their tails that they use solely for self-defense. The stingers release a poison that inflicts pain. However, not all rays have stingers. For example, the manta ray and porcupine ray do not have stingers.


Ever wondered where do stingrays live? As far as geological preferences, stingrays prefer the tropical and subtropical regions. However, they can also be found in temperate oceans. Some species can be found in deep oceans. Freshwater stingrays prefer rivers and streams in similar geological regions.


Freshwater stingrays are calm creatures that prefer to dwell at the bottom of rivers usually hiding in the sand or mud. They use electroreceptors to hunt their prey and detect predators since their eyes aren’t useful in this position.

Add that to the fact that most species are nocturnal (active only at night), don’t be surprised if your pet stingray tries to hide at the bottom of your aquarium for most of the day.

The sand should be fine and any decorations used should be smooth (with no sharp edges). Try to keep as much of the bottom as possible open for the rays to swim and bury themselves in the sand.

Breeding freshwater stingrays takes a lot of patience, space, and dedication. The females are bigger than males and have two uteruses. One female can have litters of pups from two different males at the same time.

Males have modified pelvic fins called claspers, which they use to impregnate the females. The pups usually fully develop within the mother which then gives birth to live pups (see, how do stingrays mate?.
