Found another one with bright blue eyes. Hes been living in birds nest. Someone told me he lives on the Coral?? Idk because where he's sitting looks like he's scraping the polyps off the coral

Should be cleaning them. An acro crab.
 
Yep, Trapezia or Acro crab. I have them in my tank. Harmless unless they reside in a small colony not big enough to recover from the feeding habits of the crab. They like to feed on the mucus of the coral.
