Are there "bad" copepods??

So... I had an acropora in my QT/frag tank RTN on me yesterday, and the skeleton has been covered in these copepods picking at whatever is left over. What's I think is wierd is they are even all over it when my MHs are on - and they are not swimmers, just crawling along the sandbed (and I even watched some of them appear to fight for territory)

Anyhow - here's some pics of em - anyone have an idea as to what they specifically are?

It's possibly a munnid isopod. I personally don't worry about them.

I agree with the munnid isopod. These are good guys.

Yup - looks like a munnid, thnx for the ID - Now I get to keep watching for other new critters and hope I actually don't find any
