I was planning on keeping an aquarium with a catshark or two, with a panther grouper, dragon wrasse, harlequin tusk and a moray eel (eel is undecided), and I was wondering whether a saltwater ray would be able to get along with them? I'm quite worried of having some of the other fish be stung. For context, I was particularly considering the blue spotted/dot stringray, or similarly sized stingrays.
