The Bicolor or Bicolour Cleaner Wrasse has a large range, being native to reefs in much of the Indo-Pacific.
Like the Bluestreak Cleaner, it is a very important little fish since it has a crucial job.
It has a blue front half and a pale yellow back half and it grows to 15cm long. The Bicolor Cleaners eat mucus and parasites off
a range fish including the smaller Bluestreak Wrasse, fairy basslets, damselfish and hogfish (shown above) and much larger fish including rays and sharks.
