Fresh water Stingrays

[Yom]

Ok so been seeing lots of videos on Facebook that show fresh water stingrays in discus tanks (large tanks), does anyone have experience that they can share on keeping discus and stingrays together?

Yes I did it for years no longer keep discus but currently have 14 rays. Rays are predators if they are strong enough to hold the fish down then it is a goner. From my experience adult discus should be K with rays up to 8" to 10" max after that better look at moving the rays or discus out.
