Well Zait, small fish can easily be eaten by crabs, happens all the time. In fact, they
can also find a crevice in a rock that they like and wedge themselves in it for the night
or for protection and you can miss them entirely, even if you move all rocks. BUT if you
are lucky and karma is on your side, that fish is "sleeping with the fishes". Maybe he did
not like the hammer. At least now you can get a fish that is NOT aggressive and territorial.
If there is another damsel in the tank, the prospect of being chased and nipped and bothered
to the point of death is always possible, at which time the crabs move in.
