Thanks for the comments... The jawfish is really entertaining. I'll try to get some pictures of his home, but until I do, I'll describe it. He dug out a hole under a rock, and just this past weekend we added about a dozen empty shells for the crabs. Well, he took that opportunity to fortify his home with them, so he's been dragging the shells in and out of his hole all week, setting them up just right. It's really fun to watch.
