Accord- I had the same thought. Reattach and cover with moss. It's a South American Biotope-ish but I figure I can fudge and use moss in place of algae! Hell, I'm going to have Algae Shrimp in there anyhow because I already have them in my smaller tank so it's not exact.
To be honest, I was the idiot. I'd gathered about 2 dozen REALLY cool pieces of manzanita; branches and roots. I bought a 50 gallon rubbermaid and was soaking them. This root was super twisty and forked off a few times and I watched him walk right past my rubbermaid, snag the root, and break it. I kind of yelled at him. And I could see in his eyes that he was thinking, "it's a pile of sticks in a water-filled barrel. WTF?"
