If it looks like a duck and quacks like a duck....is it a BTA?

This is about the size of a dime! It came on a piece of LR I bought and was covered by a xenia and flower looking corals. It looks like an anemone to me and it closes up when it is bothered, like an anemone? Its sooo small though, what do you guys think?

Ok so a quick search reveals that they are bad. I think it looks cool and like the way it or a few would look. However, more searching tells me to resist the urge to leave it be as IT can quickly become MANY! so it's best to get rid of it I think, thank you guys!

Kill it with fire, or better yet a laser

I found one in my tank that looked pretty cool as well. Like yourself, I thought I got lucky until I found out how invasive these things are.
Covering it with kalk paste is an easy way to kill it.
