I have had many encounters with these beautiful fish. I read somewhere about this tip, which I have used with great success. But the slurpie top sounds even better!
Build a little rubble-pile around the back of your rock-work, be sure that it has a variety of sizes of rocks, empty shells, and a few flat pieces laying flat on top of the sand, which the fish may use for the "roof" of the cave. Then I use a large mouthed bottle with the bottom cut off (Mott's Clamato Juice), and I shove it around said rubble-pile. (Of course you will have to re-scape your decor later to accommodate the new set-up).
Then I use a tube of clear up-lift pipe to fit around the mouth of the bottle. After acclimating the fish, gently pour it down the tube (that way, other fish will not bother it on its decent, causing it to jump out of the tank). You may have to be ready to keep pouring sw down the tube to help get the fish into the bottle. Leave it alone for a few days. It will build its cave in peace. Be sure to feed it in the meantime. Mine took to mysis right away.
Jawfish is great to watch, as it will pull a piece of shell over the top of its cave to "seal" the entrance when it wants to be left alone, or for a nap, after feeding time.
I usually do my re-scaping them, so as not to spook it. Do place a few large rocks around its new cave to further help it to feel secure. It will usually build a few more caves on its own later on as it feels more confident. HTH.
