Rays have different attitudes but over all they are pretty placid. Two of my rays I could handfeed, pet, even pick them up (not out of the water of course)! My current ray, is a whole other story, as he is rather onry. While acclimating him, he damaged his stinger cause every time I walked by he would flip his tail up and wack the side of the cooler! Ive hand fed him and touched him since but Im no where near as comfortable with him as my previous rays.
