My experience and reading of the Orchid Dotty, Pseudochromis fridmani is a lovely slightly timid fish that inhabits the crevices at the base of my liverock.  She is a simple excavator keeping her little cave free of debris but not enough to make a mess of the tank or corals. 
 
I can't comment on how this fish is with wrasses or other dotties but she is a great companion to my clownfish.
