Friend or Foe?

[Jascee]

These pretty little things just started covering my candy cane rock. Any idea what they are or just coincidence I watched Alien at the weekend?

Only on the 1 rock so far. In 45g tank. Everything else seems clean and healthy.

Thank you! For the uninitiated friend or foe for my tank? And why only in the one rock?
