6 Line, Midas, Chromis, Dottyback in that order of potential aggression. In that size tank, the first two are probably the only potential problems.
swap out the sixline for a carpenter wrasse--a nice pink or red on---far less possiblity of agression then the six line.
that should remove any possiblity of the dottyback becoming agressive since the entire reef will be its territory rather then competing with the sixline
Chromies can become agressive as tylt33 stated but I have found that occuring when you get a lone one left that is almost adult size---it then can start to nip fins of larger fish.
