Ok so is it possible that I have a pair of rays that are the same??? Does anyone know exactly what these 2 rays are?

Neither of them is active both are buried I threw some muscle in to the tank and neither of them moved so I went out when I came back both rays have moved a bit and the muscle has gone but do not know who ate it im quiet worried.
