Feather duster left his tube. Any ideas? (Pic)

Well I moved him during a wc. So I pretty much asked for this. Is there anything I can do? His tube is vertical should I lay it next to him. He seems to be alive.

Give it time. It'll re calcify a tube. Or get eaten trying. Sorry.

This is generally an indication of stress. Something isn't right. Most of the time it's with water quality. Could be a flow issue. Could be lighting. Can you post your most recent test results for water parameters?
