    I've just started my saltwater tank and noticing these growings on the LR. They've been in the tank for about a month now. No algae problems, I'm going to add my first fish soon but worried about these. Please tell me what are these hair like tentacles and if they're harmful or good. [​IMG][​IMG][​IMG]

    These tentacles are on almost all the live rocks I got and I figured they were feather dusters, but these are mostly in singles.
