Currently I have a large red mushroom that is about the size of a CD. He currently is in a box inside of tank A and he had attached himself to the bottom. I am wanting to put him down into the display in Tank B and am looking for recommendations on how to do it. He is not attached to a rock or anything in tank A, just the acrylic box. Anyone have any suggestions on how to get him detached from the box and attached to a rock so I can move him?
