<span style="color: black;">I bought a chunk of live rock yesterday, gave it quick iodine dip, rinsed it (nothing came out), then placed it in my tank.</span>
<span style="color: black;"> </span>
<span style="color: black;">Today, I took it out to break up into smaller pieces; I'm replacing my bioballs with it. After placing the fragments in my sump, I went back out to clean up the sidewalk where I had broken it up, and found a worm in the rubble. I placed it in a bowl with saltwater. It began about 1 1/2 inches and very plump at one end. Shortly thereafter, one end began telescoping one and stretched to about 4 inches. It is pale tan-colored with darker bands on the part it telescopes out, which gets narrow toward the end. My camera is at work, otherwise I'd provide you with an image.</span>
<span style="color: black;"> </span>
<span style="color: black;">Anyone know what it is...and whether or not I should put it back in my tank?</span>
<span style="color: black;"> </span>
<span style="color: black;">Many thanks,</span>
