Small bicolor blenny went missing

Has anyone had a bicolor blenny that dissapeared for over a week? I put mine in the tank i saw em once last week after that i never saw him again. ? i checked all around tank in filter and all but no sign... hes kinda camoflauged but still ive stared and stared in tank and dont see em. i have a tang two yellow head jawfish a clam and a couple of anemones. could an anemone eat em?
 
if the nem was big enough it could, also they like to hide in and under rock and he might have crushed him self, but he may just be hidding in a rock
 
I had one that carpet surfed and I found him quick enough to get him back in the water and he went surfing again about two weeks later. Check again in small areas around the tank.
