Coaxing a fiddler crab into view

[jagster]

I've apparently inherited a fiddler crab when I purchased live rock for my tank over 5 months ago. At that time, I did see a small crab on one of the rocks as I was cleaning it. I couldn't get the crab out of its crevice, so I forgot about it. Since then I have never seen the little guy in my tank until the other day. I caught a very brief glimpse of something scurrying across the sand bed. I finally found it, and if it is the same crab I found 5 months ago - he has grown up!! It appears to be a fiddler crab, brown in color and about the size of a golf ball, maybe bigger. Since I haven't been able to find it again. Anybody have any ideas how I can lure this freebie out into the open so I can get a good look at it?!?!?

Depending on what you have in you tank, you could drop in a piece of silverside, shrimp, etc. in an open area, and sit back and watch. You could also try tieing the same to a piece of thread and watching either with the lights on, or try it with them off during the day.
