New hitchhikers.. Help identify.

I recently purchased a few colonies of different polyps and noticed some new hitchhikers. One is a snail which I think is from the Limpet family.. Looked all over the net and have not found same spieces. I Want to make sure it won't eat my corals..

Next is a Aceol flatworm that I noticed in my refugium.. Think it is harmless but just want to see what you all think.

Yup, that looks like the kind of FW that doesn't bother anything and doesn't bloom to nusiance populations.

The first pic is a stomitella snail(spelling)they are a good hitchhiker.

Thanks guys!! Looked up info on that snail and that was the one. Nice when you get hitchhikers that are a positive impact for the reef set up..
