My Snail Came With A Feather Duster

Thinking the duster will eventually detach itself. Your thoughts and thanks all.

It's a little hard to see the duster in your photo but if it has a mucus tube it will probably get bigger and then rehome. If it has a calcified tube make sure it is really a duster. Very small dusters are common in/on live rock and they stay small. It will probably just stay on the snail. The reason I said to check is to be sure it is really a duster type crown. It could be a vermetid snail which doesn't really have a crown it is more like strings. If it is a vermetid, pull the snail out and scrape it from the shell. They can reach nuisance levels.

Its likely as it is common to have a tube worm which sends out that fan to capture food
