One of them is a snail. I have no idea how it got into my tank though.
Another is a worm. Is it a bad worm that I should exterminate?
I caught both of them I just need to know what to do with them now!
the worm looks like a bristle worm, or a fire worm? the snail looks like a cerith snail. im not sure about the worm but if it is a cerith snail its fine

first snail looks a lot like a cerith but it is probably a turrid. turrids are predatory carnivores, they will eat small bivalves and the like in the wild. In an aquarium they mostly scavenge. I have seen that turrid, they have them on the texas coast everywhere...species name on the tip of my tongue...this si going to kill me.
the drill thing threw me off for awhile. Gray Atlantic Auger or Salle's Auger, my bet is on the gray atlantic auger. They eat clams, so be careful if you get a crocea. Other than that they should scavenge and eat snails, small worms in your sandbed and small bivalves, but who has small bivavles usually?
