hi everyone. I just bought 50lbs of live rock from someone on craigslist. Can someone help me identify what are these stuff growing on the rocks are? and are they bad or beneficial to the tank? I attached the pictures. I'm questioning about the little branches that are growing out from all over the rocks. The other two pictures show some transparent tube thing on the rocks. Are they safe to keep? Thanks!
