My buddy just recently purchased four 4in motoro rays. He had them in a 400 gallon setup with plenty of filtration. Moved out all the other fish into other tanks so the rays can adjust. Lost 1 the first night, the 2nd one the third night and all for within the wk. All refused to eat. He tried all kinds of food including bloodworms, white fish, frozen shrimp, ghost shrimp, krill and night crawlers. None of the rays seemed intresed and refused to eat. Im at a loss on what to tell him.
