I think the mushroom frag that had come unglued from the rubble I put it on in the 10g turned up. Last night it was about 3 inches further back in a corner than now. Do these move on their own? Should I just leave it and see what it does, or do I need to pick it up and glue it to something?
All the dark flaky pieces around it are new too.
