Any idea what this might be? Also, should I get rid of it, and if so, how? Also, I have some aptasia that is in my filter column (Coralife 32 gallon all in one) and I am not sure how to get rid of it. I have a peppermint shrimp, but it doesn't have a taste for it apparently. Any help would be appreciated. Thanks.

That’s a vermetid snail - they range from harmful to benign, but are best to remove before they spread too much. They release a mucus net that can irritate corals.
To remove, break off at the base and put super glue over where it was.

Agreed, looks to be a larger vermetid.
