My 16 -18inch ripsaws in with my 1 year old retic teacup and their has Been no problems at all. They do really well together and I would suggest it since rays are messy and the cat will clean up after them!
Thanks guys I've had him for 2 years and he was 3" when I got him. The rays do bite his tail every once.and a while. He does steal some food. Will definitely clean up all left overs. He also sifts threw the sand, it shoots out of his Gill plates.
