My boyfriend and I bought our first saltwater tank recently. So far we only have a few clownfish in it, and were looking to add a few more fish. well, 6 days ago we went to a local saltwater store and purchased 2 live rocks. Almost every other day we're finding a new "something" coming out of it! I've googled what I think it might be and it doesn't seem like any of it would "hurt" my fish, but I'm afraid to invest anymore money into fish if I'm going to have bigger issues. I would like some clarifications on this issue. So far I think its Aiptasia, a asterina starfish, a bristle worm (ewww!) oh and a few snails.. also I have no coral in my tank, a lot of what I seen said my critters are only damaging to it.
