The Mystery Wrasse, Pseudocheilinus ocellatus, also known as the Whitebarred Wrasse or Fivebarred Wrasse.This Wrasse has slender vertical white bars that get even thinner as it matures, sometimes even fading on the adult
The tank should contain a thick sand bed, along with live rock creating plenty of caves and crevices for retreating into to if needed. They may also bury themselves in the sand and will use a cocoon if they feel threatened when they sleep. Using a lid is also a good idea as the lined wrasses have been known to jump out of the aquarium. Mystery Wrasses are diurnal, which means they are active by day and sleep at night.
