Hello and welcome to R2R! Is your rock "live" wet rock or was it dry rock?

Dry

Ah, ok. When first starting to cycle lots of critters can pop up. Usually they are harmless "filter feeders" and while you want to keep an eye on them, they usually just go away by themselves. So check out the link I sent you so you can keep an eye out if any develop into the harmful types.

Your tank is cycling or likely already cycled. Test nitrate and ammonia. This is a good sign that your tank has life in it.
