Yep. They do that.
I am slowly replacing the fish I lost in the power-out, and I chanced on two yellow watchmen (male and female)---young. Real young, only about 2". I have a 105 gallon tall quarter cylinder with a LOT of rockwork.
I put them in. I expect to see them again in 2017 when they're bigger, bolder, and perhaps paired.
It's the nature of little fish to dodge big fish and stay out of their way.
It's the nature of gobies to dig a hole under rockwork or (some) to hide in coral and often to do it on the back side of the rockwork where it's quiet and they can feel safe. A house is full of bumps and thumps and voices, and all of those take getting used to.
So don't freak when your new goby/wrasse/etc doesn't show up immediately. And don't freak if they outright disappear for a month or so. I had one relocate for three months. Don't know what ticked him off, but he took his sweet time re-establishing his den front and center.
I'm not keen on pistol shrimp. Had one go rogue and kill his partner and several other fish: had to unbuild the tank to get him out (tiger pistol/yellow watchman combo.) I've had candycane pistols vanish right into the downflow, and if something is that small and inclined to head for the downflow slots, he'll do it again the moment you bring him back. Other people have found them good citizens and fun. Your personal mileage may vary.
I'm very fond of gobies and blennies, however. They're little cigar-shaped fellows without a lot of impact on the fish load, they're pretty nervy, and funny. And not much picks on them. Damsels and tangs ignore them (unless the tank is too small for the damsel or tang.) And they're a bright flash of color.
Someday my fish will come...
