I actually went on this excursion while in the grand caman islands it was awesome. These reays come by choice to get fed really well by people. This is over 2 miles off the coast, on a sand bar. The boats come in with really good fresh cut up fish, and shrimp and stuff, and the rays come in as soon as they see the boats. If this was so miserable for them they wouldn't keep comming. And I am a ray lover and have 2 of them. This was the start of me wanting rays it was so cool to be so close to these wild beautiful animals.
