copper banded

Which fish if more affective at controlling bristle worms at their small stage? Copper band fish or Wrasse????? The Copper band is a great addition to the tank and I found a wrasse that’s pretty unique looking as well but not sure if it’s a certain wrasse or all wrasse that eat bristle worms

Hi everyone, I noticed a few days ago that my CBB’s right eye appeared abnormal( please see photos). I am unsure if the eye lesion was caused by trauma, infection, or parasites. Any help would be appreciated. Thank you
