I have experience with Lionfish and Freshwater Rays..
I am looking into setting back up a Lionfish species tank, but was thinking how cool it would be to have my favorite 2 fish togethor.
I would obviously research sizes and appropriate species for the tanks im working with, which would be either 180g or 375g..
My curiousity is if the overly active stingray has the potential to injure himself or the lionfish with this hyperactivity.. Not worried about the Lionfish botherng the Rays, but rather the rays swimming over and around live rock and not realizing a Lionfish was hiding and poking themselves..
With that said.. I figured I would need a ton of huge open space for the ray to swim, and some live rock caves in the corners for the lionfish..
