help identifying this guy

Just set up a new rsm 130 tank, cycled it fine. Everything back at 0. Done 25% water change and added the cuc. I bought 5 turbo snails. I thought 1 had lost its she'll but tonight I find all 5 snails plus this little guy that looks like a snail minus it's she'll. Any ideas. He's out and about now and not been seen until yesterday. No idea what he is but defo not a shell-less snail. Any ideas.

Ps how do I post a picture on here
