Ive had rays in BOTH bare bottom and sand. One thing Ive noticed is that when kept in sand the rays are much more active shifting through and exploring the sand.



Given this behavior, could one say that its more healthier for rays to be kept in sand since they are exercising and not so bored?
Thoughts?
