What is the best way to catch a bristle star?

[Adam'sShrimplet]

I have a black bristle star in my tank that I never wanted in the first place! He is quite a tricky bastard. He hides very well inbetween my rock and will barely come all the way out. I am quite certain that this unwanted guest has killed my red scooter and my spotted mandarin, so it is his time to go. I know that they are nocturnal but does anyone know a way to get him out with out having to tear apart my enitre rock set up? Any ideas or suggestions are greatly appreciated.

later in the evening with a suchion cup, attach a piece of frozen shrinp to the front corner away from any rocks. When he comes out to feed, grab him by more than one leg and put him in the sump or a bucket.
