Thanks, Eric.
My fuge is a bit crowded with various macroalgae and the lights are pretty bright (2 65w PCs, white and actinic), but I might move it there if it doesn't do well in its current location. My Niger Trigger kept moving it from a nice little cave between the rocks and dumping it in the sand, so I IC glued it to the underside of an overhang. I read somewhere that's where they occur in nature. Should make feeding a bit tricky, but there are plenty of pods and mysis in my tank. I'll let you know how it goes.
