It looks kind of like a flatworm of some sort. Most of the time these things are harmless, but there are certain varieties that can irritate your corals.

My vote is a baby snail or a pineapple sponge.

They slither. They move like a snail and their tail have split end. They're all over the place! I want them gone,any advice on how to?

Flatworm!
where there is one there are hundreds.
can't tell if its planaria or the common brown flatworm.

Try to ID it the best you can

Well your best choice is FLE
BUT if it the common brown flatworm (not planaria) it will not eradicate them.
