Brittle Star in Sump Baffles. How to move?

[fishnu]

I moved a live rock into my refugium to populate it with pods. Unfortunately I did not know that my brittle star had taken up residence in the rock. After not finding it for a couple of days, I found it in the (narrow) baffles of my sump, merrily feasting on the detritus there.

I would like to move it back to the DT but my space is very confined, and I can't reach in. Does anyone have any experience in "starfish fishing" or trapping? I was thinking of tying a piece of shrimp to a thread and gradually teasing it out, but I would like anyone else's ideas as well.

Thanks in advance
