In general, Rays are very docile. They will pretty much keep to themselves. This doesn't mean that they can't be nasty every once in a while. As they sexually mature, Rays become more bold, and will sometimes act out on other fish. *edited for length* I'm not saying that Rays are nasty like most Cichlids, but they do have their moments. The best way I can describe them is that they act like little kids...they always have to touch everything.

Of course, be VERY wary of any Ray's spine. It will deliver a very painful sting. The spine is shed about every 3 months or so and replaced with a new one. It should not be a problem unless your hand goes looking for trouble.

Rays should be kept with more reserved, unaggressive fish. They are very vulnerable to being picked on. Good choices are the lesser aggressive Arowanas, such as Silvers and Blacks. Gars would be another good choice. Bottom dwellers, such as Polypterus and Clown Knives, are also a consideration. Stay away from curious, territorial, and aggressive fish such as Oscars, Jack Dempseys, and other large Cichlids.

You still need a large tank, a pond is an option.
