Where did my Wrasse Go?

So I cant fine my six line wrasse. I have a FOWLR 70g tank with two clowns, a chalk bass, and three blue green chromis. The six line wrasse was added about a month ago at the same time as the chalk bass. A few days ago I was getting ready to feed the fish and I couldn't find him. Normally the fish all come to the top front of the tank when its feeding time, the wrasse never came out. I have been looking for him ever since and haven't seen him one time. Last night I did my maintenance and water change. I also removed all the rock to clean it of some algae and I re arranged the scape. Still no sign of the wrasse. I checked the sump, filter sock, built in overflow box, the floor around and behind the tank, and in the nooks and crannies or the rocks. Still no sign of the wrasse. None of the fish have ever shown any signs of aggression and I never see them even try and nip at each other.



Where could he have gone? Kinda confused.
