need help ID'ing....

[Mini_Reef]

A few months back I noticed a pink-ish thing crawling on my LR.....usually at night. I asked my "fish lady" at the pet store, and she said it was probably a bristle worm. So I bought this thing called a "Trap'em" and have been using it every other night, trying to catch a worm or two.
Well, last night, I found that along with my nightly catch of starfish, there was something else in there!
I'm not sure what it is, and the only camera I have is a webcam, but I think i got at least one decent shot of the "thing".
I also took a few of the starfishes that I caught. I have so many in the tank, and I've been told that removing a few won't hurt.

Can anyone help me ID this little guy?

Another shot....not quite as clear though


Starfish....

It looks like a gammarid amphipod. They're harmless scavengers.
