It is a hit and miss with the Dottybacks and Damsel fish the vast majority are territorial and can be very mean to tank mates yet there are ones that are known to be nasty tank mates that in your tank could be the perfectly behaved fish. Basically stock at your own risk with Dotty's or Damsels 
 
Have you considered cardinal fish or any of the fairy wrasses?
