I pretty sure there are, my LFS sells what they label "Teacup Stingrays" but apparently they become massive and need massive tanks and eat any small fishReally cool pics. I love the rays. Rays are one of my favorite fish. Is there any freshwater species of rays? I think I'll post a topic about that.
On one of my other posts somebody said "forget the fish get teacup stingray, much funner" I LOLed really funner? It was my post about restocking my tank.
