Notes: Wrasses are common members of the world's coral reefs.  They typically are carnivores feeding on small invertebrates that inhabit the reef.  Many have different appearances as adults than when juveniles.  And several others will display differences between males and females.

Wrasses should be provided with a number of hiding places.  Caves and crevices in the live rock make excellent places to hide.  A number of the wrasses also feel safe burying themselves in the sand for a nap or temporary disappearing act.
