The best food for rays are worms...bloodworms, blackworms, and definately earthworms!! My ray comes charging when he sees my hand in the tank holding a yummy wormie!!

They also like live ghost shrimp and any fresh seafood like mussels, fish, etc...From what I've read, most won't eat pellets and I know mine doesn't. They'll eat guppies and other small fish, too.
As far as tank mates, sure, but like TnCgal said, be careful! Not too mean, and not too small...If a fishie fits in the rays mouth consider it lunch!

Another thing is to be careful w/plecos. Some like to latch onto rays and that can really hurt &/or kill them. I had a big 'ol rhino pleco and he managed to hickies on his back!!

Luckily, he is healing fine and Mr. Pleco has a new tank to call home. I now have a little 3" rubber lip pleco in w/my ray and the two do fine together.
Getting stung, from what I've heard, can hurt like a B*tch for at least 3 days and cause a lot of swelling...however, the likelihood of your ray stinging you is pretty slim as long as you don't make sudden movements to startle it. They'll get used to your hand in the tank if you hand feed and will associate it w/food, not danger. Most rays would rather run than sting.
