Besides tangs, the jawfish are my favorites. They ARE jumpers so make sure your tank is covered. They do hide alot at first but when they get used to their surroundings they emerge more and more.
The one I had I lost because he jumped. Have no idea how he found his way out with a cover in place but he did. I am setting up a 150 that is now cycled and ready for fish. It has a 4" dsb and lots of rockwork. I will be getting 2 of the pearly jaws to go in there. I am sorry that I don't have any pictures.
Good luck. You will love him!
