Missing wrasse

[Proteus]

I have a lineatus wrasse which is approx 4". Two days ago my dimond gobie divided to make a townhouse complex. He made 4 new homes and made quite a mess. The tank was quite clouded and this is the last time I saw the wrasse. All other fish are fine and swimming around. The tank is covered overflows are blocked. Not in sump no where to be found.

Water peramiters are good.

Has anyone had a wrasse hide for a extended period of time
