So I was just wondering if there are any freshwater Elasmobranches besides the species that are in the family Potamotrygonidae and also if you ever seen them available in the trade???
Just curious??? Freshwater Elasmobranchii????

You get several euryhaline species - those that move into freshwater - such as bull sharks and a few stingrays. The Niger stingray, Dasyatis garouaensis comes to mind. The problem is, Elasmobranches generally maintain high levels of Urea in their blood and tissue for osmoregulation, in freshwater this isn't needed so they release huge amounts of ammonia. Freshwater rays have managed to develop similar methods of excretion to freshwater fish. It seems like Potamotrygon genus seems to be the only group in the order to permanently live in Freshwater, or is at least the only studied group that does.
Bull sharks are able to tolerate freshwater for long periods of time. If you know where to look they are available in the trade, however the requirements to keep one would be extensive, and very pricey.
Wait really I’m surprised to here That they are in the trade the biggest shark species I have seen for sale are nurse sharks but damm thats surprising.
Yah I've seen them at at least 1 shark dealer, I'm sure there are others as well.

Only The Niger stingray or Giant Asian stingrays that I know of, both pretty much unheard of in the trade.
You want to set up a shark-sized saltwater aquarium on a Teen budget?

Preferably not but my mom is making a saltwater aquarium soon so its an option. Thats why I want a freshwater elsmabranch because the species in the family Potamotrygonidae are illegal in florida also have you guys heard of atlantic stingrays I heard they can live in freshwater is this true.
As stated above, saltwater fish in Freshwater conditions release tremendous amounts of ammonia, more than a filter would generally handle. I'd stick to regular freshwater fish.
