Missing wrasse

[kien]

I have a royal pencil wrasse that I thought was a goner for months. That is until one weekend when I noticed that his schedule is 2pm to 5pm without fail. I'm not sure what he eats because he misses both morning feeding and evening feeding schedules. I only see him on rare weekends when I'm actually home and looking at the tank between the hours of 2pm and 5pm

I had a coris wrasse that had the same schedule. But thrived till he went carpet surfing. But I've fixed the jumping problem
The tank is completely covered with no way of getting out so here to hoping he is hiding for a while
