hey steven , i see nothing too worry about at all with your guy from the pic . my guys have had all kinds of injuries worse then this , and they always heal up ( so far anyway ) .
as far as drop eye im convinced its from impact injuries like slamming there heads on the lid or something in the tank . i have witnessed it happen on a couple of occasions now with my own eyes were the fish freaks and smacks itself on something and immediately the eye drops . sometimes it seems to almost go back into position a bit but not fully then if the fish smacks it self again it drops again, but once it happens it seems to always be there . i have wondered about netting the fish and trying to manually pop the eye back into place but the catching of the fish might cause it to bang its self up more so i haven't tried it
