I bought a flasher wrasse about a week ago and as soon as I was able to safely put him in the tank he instantly went into hiding he looked dead honestly but after a while he got up and swam into a hole and I haven't seen him since not even when I feed my other fish I have a yellow tang and two clown fish and spinny urchin and a few corals but does anyone have any ideas on how to get him to come out I don't even know where he is hidin at this point either I don't want to pull things apart and stress my other fish out but I also don't want this wrasse to be dead some where in the rock work producing ammonia
