Sorry for the dumb question but I recently got my first ray and it is great. It is a 7" motoro. It seems that when lights are off, it likes to hang out toward the top and sits on my return pipe. I don't really like it up there because my aro has jumped and hit tops a few times ripping its scales pretty good. I don't know if ray is bothering but is it possible for rays to sting and kill other fish?
