My son was running late tonight from work, stuck in traffic. He called and asked if I make sure his new ray ate . Well I was feeding my pack of Cl's so I diced up some green mussels and placed it by the ray...He went crazy eating as much as he could chasing some of the geos away. Anyway I'm going to nick name him Hoover the way he cleans the bottom of the tank.. Thought I'd share we have the ray eating prawns, earthworms, squat lobster,Hikari pellets and now green mussels, what a metabolism they must have.. what unusual foods are you feeding your rays......? What about beefheart?
