    Cool idea! Did you drill into the PVC or just the Shell? I've tried to use cut PVC for gobies and jawfish, but they don't stay for more than two weeks.

    I drilled a whole in the pvc also.

    The jawfish that I've had in the past nearly disappear for a week and then emerge with a full den. The pearly eventually relocated to center of the tank, facing the glass, where I feed. Did you add them directly to the tank or did you quarantine them first? The draw to DD is that they supposedly observe their fish for diseases and make sure they are eating before shipment. They don't treat the fish unless it's showing signs of disease, so they're not ich free. Some people have said they doubt the observation period even happens at all, but I've never received a bad fish from Diver's Den. I normally buy fish that don't quarantine well from Diver's Den, but I haven't had good luck QTing lately and I may just buy them all there. 

    I just added them straight to the tank. I haven’t seen any signs of ich or internal parasites.

    I built a home for my jawfish. When adding him I just held the net over that spot until he went in. Has been there for about 3 weeks now.

    To be honest, I have never kept this fish. The book on fish species that I have at home and the websites selling the fish don't mention water temperature. I did find a reference from Bob Fenner in, A Cool Fish in MOre Than One Sense: The Blue-Spotted Jawfish. Mr. Fenner is an authority on marine fish and I trust his recommendation. 

    "The practical implication is that water off the Californias is appreciably cooler than the same latitudes in the West Pacific, with the habitat of this jawfish being mostly in the upper 50s to upper 60s, and rarely lower 70s. Being an old timer in this interest, including the hobby, trade, and sciences, I have seen a few cycles of cool to colder water organisms sold (or may I state misrepresented) as tropicals, including Catalina gobies, Garibaldi, Metridium and Tealia anemones, moon snails, many types of algae, etc. None of these will live for long in too-warm surroundings, and neither will this coolwater jawfish. No matter where you live, it is very likely you will likely need to buy and run a chiller to keep this fish."

    Thanks for bringing it to my attention. My aquarium runs between 74-76 without a heater or chiller and I think it's best to avoid species outside of these parameters. I've kept both the Pearly Jawfish and the Tiger Jawfish and both come from the Caribbean. I liked the Pearly Jawfish the best out of the two and will probably go with that one. My tank is large enough that I could try multiple and they would have enough territory. Another thing to consider is sand depth. The Tiger Jawfish was kept in 5" of sand and he made his burrow straight down vertically. The Pearly Jawfish was kept in 3" of sand and he made his burrow diagonally. I need to clear the sand bed of 20 or so corals and then look at the feasibility of adding more sand. I have 2-3" of sand right now and adding 1 more inch may be too much trouble. 

    I recently picked up a pearly jawfish and golden Midas Blenny off diversden and they both came in healthy. The jawfish took some time to get comfortable but now comes out and swims with everyone else.
