Was afraid of that. Definitely have to separate. Those are the nice Lents isn't it. Shame you are so far away. Now I know I am definitely not putting my pair of Marms with my rays.
I agree with Jerry. While a damaged tail probably isn't going to kill the ray, the pikes may step up the assault and the stress of being attacked all the time may very well kill the ray.
Moved the Pikes into my wet/dry for now. It took about 2 hours to catch those little pricks. I am willing to sell them so if any of you happen to live close to me let me know.
My Stingrays are my favorite fish. The female even comes to the top of the tank when I have the lid open, rests on top of the ledge for a few seconds, lets me pet her and/or feed her and she goes back down. She is one awesome fish!
