What in the world!

I love my tank! It’s like things grow out of thin air. I know the pictures suck but can someone tell me what this is? Caught him on my sps coral. Are they harmless or am I going to wake up to my corals gone? Please any help! Thanks

Looks like a Stomatella snail. Friend! Awesome CUC.

The Stomatella snail is a common aquarium hitchhiker. If you find one in your tank, should it stay or should it go? Is this mollusk an aquarium friend or foe?
