Weird Green Stalk With Fan

[FortLivingRoom]

My tank has been running for 2 months. Lights have been on for a week. Just noticed this green stalk on a snail yesterday and thought it was just GHA, but it has a little fan on the end that you can just barely see, what is this?

Also, there is a flat green disk that is round that just started as well?

Tube worm which uses the fan to capture its food. If you wany it gone, place a dab of Gel super glue over the hole but theyre harmless.
