I was thinking about picking up a jardini for my tank, as I love how mean and badass they are, but I have also read that Jardinis and rays dont play well.
what size is your ray, and what size is the jar you wanna get. tank dimensions will also help. if you get a small jar and put it with tank mates they will be nicer than when kept be it self. when its kept by its self they are very aggressive and will most likely take out other fish. i
