#identification

I found this snail in my tank after about 8 months of having my tank and I have watched it grow since it was a tiny baby now that it's big and I still can't figure out what it is. I have 3 zombie snails, 3 margarita snails, and two conchs. It looks similar to a zombie snail (nassarius snail) but...

Need help identifying this type of mushroom coral it’s tentacles look like those on a branching hammer.
