blue/gold amphipod

[Grey Reefer]

I was checking out my tank this night when I spied a blue and gold amphipod. It was the coolest looking thing I'd ever seen. It's body was cast with a deep royal blue with a golden interior and was about 1/2 an inch long. That's the best way I can describe him. Has anyone else spotted a pod in their tank like that?

Sorry no pic for this little guy(no camera handy)
