Hide-and-go-swim: How long was your fish "missing" before it reappeared in your tank?

[PotatoPig]

In perhaps a more unusual case:

I have recently had a coral go missing.

I had a War Coral approximately the size of a golf ball that has disappeared without a trace. My suspicion is that my engineer goby buried it, but from an investigation of the sand around where it was last seen it doesn’t appear to be in the vicinity…

Had a model citizen Yellow Coris Wrasse vanish one day. The tank had a tightly fighting lid and no chance of anything in the tank being big enough to eat it. I moved the tank a few months later and never found a trace of it.

My wife says that I with meaning only chose fishes that can disappear for a month because I always be glad when I found them. some of my fishes has take years before they dare to show up regularly in bright daylight.
