I think it's ok to carry the species as long as you check out the buyer. I would say that the majority of people who own rays know what they are doing, and yet rays are pretty hard to keep, in terms of equipment. It just depends on what people perceive the fish to be. People look at rays and think wow, big expensive fish, better leave it to experts. People see tinfoil barbs and think, how cute, I will put a couple in a 10 gallon tank.

I think it would be a good middle ground if you didn't regularly stock them, but maybe kept one or two in a big display tank. Oscars are pretty neat fish.
