What is a hitchhiker?
A hitchhiker is any organism that is introduced into the reef tank accidentally or incidentally usually through the introduction of live rock into the tank.  Many people panic upon seeing anything unexpected show up in their tanks.  Although some hitchhikers can be detrimental to the tank, most are not and add to the diversity and interest of the tank.  Some are even beneficial.   Another way to look at it is that all organisms introduced into the tank attached to live rock are essentially hitchhikers.
