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
