Unidentified species in the aquarium. It shares a tank with the Blacksaddle filefish, the Valentinni's sharpnose puffer, a yellow tang and the snowflake moray - Aquarium - Chester Zoo - 28/11/11
from the photo the whitish area looks like damage. The eye doesn't look good either. A while ago in one of the Chester threads someone (bongorob?) said the whitish area has decreased since the photo was taken. If it is Cephalopholis urodeta I'm assuming it looks the way it does because it has been through some sort of trauma (hence also the dark colouration).
EDIT: its weird the sign gives it the white face as well though (?)
