We've had them disappear in our 180 when we had it running. They sleep in rock cavities. It was funny to watch the reef as lights-out was approaching because all the chromis would "practice" backing into their night hiding niches, then come out again, then back in, then back out. All this went on for a half our or longer. It was like someone parking their car in their garage for the night, but not getting it right the first, second or third times
I never thought of it until the other day when we found that big bad crab and wondered if that's how some of the smaller fish in the 180 went missing. Could've had a predator in the rock and not known about it.
Last night had another glimpse with our trusty flashlight of the second crab in our 42. Looks quite a bit like the first big baddy, but only a quarter of the size. He was on the sandbed near the back of the tank, inpretty much the same place as we'd seen it before. It'll be harder to catch this one, but now I'm a determined crab catcher, that's for sure
