Molusc squurting sperm? ID help

[Reef_Chief]

I just glanced iver to my tank and could see poofs of what looked like smoke in my tank ejecting from off my rock. As i got close i could see some sort off molusc that i havent seen in their before and cant seem to find anything matching online. It was almost standing up verticaly and ejecting what i presume is sperm. Its shell on top is much smaller than its soft tissue. I do have a video but it wont let me upload it atm. I will attach some pics l. Hopefully someone can ID this moluscc for me.

Yes you are correct on your determination of that snail. Good for the tank!
