I have a MIA fish from a fish fight this morning. It has been about 3 hours since I saw him. If it was killed in the fish fight is it necessary to move all of my rock to find him? I don't want to leave a dead fish in the tank but don't want to move all of my rock to find him either. No matter what I'm going to wait for at least 6 hours before doing anything just incase he is hiding from those mean fish that beat him up.
