I am a newbie. I got some free silver Xenia and a couple of loose mushrooms yesterday from majicmike yesterday. The Xenia was removed from glass on the side of the tank and the mushrooms were on the sand. I though I had secured everything well with rubberbands last night. This morning when I looked in the tanks both were gone. My question is should I look around and try to find the pieces or let them find a place they like? I have heard of mushrooms releasing and floating around tanks if they don't like where they are placed is the same true of xenia? I have a 72 gallon that has been running for 2yrs and have green polys and yellows polys that are happy and reproducing and my water chemistry looks good. Thanks
