need help identifying a few things but no pictures

[tigertiger]

Recently I bought a few new corals and have noticed many white spiral-shelled snails that are about 1-2 millimeters long. They normally come out at night. I also noticed transparent worms/tentacles coming out of a tubes in my sand bed. The last thing is very is odd. After lifting a coral piece, I noticed a small crater on the rock that wasn't there before. When shining a light over the hole I notice a black critter or worm retracting into a hole of the crater. Is this something to be concerned about? Please help, thanks

WELCOME TO SWF....it is often hard to I.D. things w/o pics, BUT here goes
1. Look up collonista snail or a sundial....Collonista GOOD....Sundial BAD
2nd...not sure...look up spaghetti worms, tube worms....etc
3. could be a peanut worm....(harmless) or a vermitid snail........
google these things

could be pyrimid snails, which will kill clams and turbos.

uh oh.. i looked up pyramid snails and those were it. is there a way to get rid of them or should i just pick them out one by one? I tipped over the coral the look into the hole again but didnt see anything in it. Ill check again tonight. thanks for the replies
