Hi, I have things crawling in my tank that's not suppose to be there. I have a white slug looking thing, some white string looking,worms!? And can feather dusters be tiny? There's little tubes like feather dusters and they look like feather dusters. Smaller than a pencil eraser. Any ideas? I don't know what to do about the worms or slug looking things. must of came in the last bunch of live rock i got. Is this normal? Should I freak out?
