What's the best way to tell how old your ray is? I have an 7-8 inch motoro and am interested in finding out how old he is.
rayman;2328729; said:Size at birth and growing rate can widely differ, so size is unsuitable to determine the age. In my captive breed pups the first stinger is shed about 6 months after birth. This is possibly a way to determine the age. But this may vary too.
