i think u should make a sticky on "Safe and Common Sting Ray Tankmates" i say this not only because I would like to know, but people ask this all over the stingray forum and providing a sticky that can certain individuals like me (Beginning the hobby of owning rays) or exsperinced ray owners that may want to add some large tank mates if they get larger aquariums. Please Make That Into A Sticky because it will indeed be very very helpful.
