What do I do with this

[rossb]

Well I have pulled all of the real live rock out of my tank and placed it in a 33 gallon tank (I am trying to exorcise a demon something...maybe a mantis). I rinsed it in fresh water and it is now in a tank. First a bunch of redish bristle worms came out of the rocks and then some whitish ones and now I have a couple of tiny start fish on the glass that are about 3/8" across and having about 6 legs. What should I do with these critters? Are the starfish reef safe..sorry too small for a picture?

In taking apart my tank I found the remnants of many hermits, I think I put in 30, and now there are none.
