Yes i believe so. Silvers aren't bred for genetics they are mass bred for money and due to the fact they are all mainly captive bred not for proper genetics they usually develop some sort of drop eye. Now a wild caught silver won't likely develop drop eye much like the black arowana. I am not saying it's correct but it's what I've heard and logically speaking it sounds right.Is that why the black aros don't get this condition,because they are not captive bred?
