I believe that is a hydroid.
not a good thing but normal.
+1 - Pretty normal to get these, especially with a new tank. These particular hydroids are harmless IMO. I still see them in my tank once in a while.

Staurocladia oahuensis, a type of "walking" hydromedusae. They do have nematocysts, but generally show up, and like so many other critters, disappear while in an aquarium.

Congrats!
