 I will say tho that the other fish ran away from my large tomatoe when he was defending his turf. The orchid didn't seem to care.

 Orchid dottybacks are the least aggressive of the bunch except maybe the olive, your experience is typical.  The dottyback Carmen is asking about is a Pacific species and quite rough on tank mates.  In other words, 
IT'S COMPLETELY DIFFERENT.
Carmen, if you have a 50g + tank you will probably not have a big problem.  The fish will pick out and defend a territory but there is lots of room for others.  In a smaller tank it wouldn't be a good idea.
