thanks for the response.there is so much going on in my tank since i put the live rock in that i am not too sure what is good and what is bad.

Usaully when you get properly cured live rock the good stuff seems to stay, but I know of some bad stuff on very few occasions popping out, I have some a lil bigger all over my rocks, when they hatched they look like small jellies, called my LFS explained to him what they looked like, he said they were good, so far I can have at least 50 or so swimming around, they have dark yellow color to them, possible you could have the same, wish I could tell you the name, I'll try to find out, oh the bigger ones are the size of a pee, just more flat and they swim like a jellie.

Hi boba40, sounds to me like they are copapods. Reach in and see if they are hard but be careful, as you feel one, it should have a point to it and it may prick your finger. If they have 4-5 legs they are little star fish. The latter can get to be troublesome as they multiply very fast.
