I looked on my live rock today as soon as I got it(I was excited) to see these tiny things, almost transparent with a bunch of tiny legs running around on the rock, any Idea what they are? are they bad ?:(

Do they look like little clear or white bugs? If so, they are pods. They're good for your tank. Fish and corals find them yummy.

Alright, yeah thats what they look like, thanks!

Make sure it's not a predator snail.
