Most people that choose to keep a Ray are not well experienced hobbyists. I had no experience with Rays so my first Ray, a male Blue Spot Ribbontail, died because of underfeeding, and perhaps loneliness. Since then, I have learned much about feeding and how to keep them. The pic above is the current female Blue Spot Ribbontail Stingray, very happy and healthy, I might add. But this requires extra filtration. I have a 4-6" bed of Oolitic sand, and tons of macroalgae growing in both the tank and the Refugium.
