semi aggressive tank suggestions?

i have a 55g i have two clowns a blue damsel and a green clown goby im am going to be adding a red elongated dottyback. i want to add one more fish an suggestions. nothing that isnt semi aggressive my damsel will kill it

 

I would be more concerned about your Dottyback being the boisterous culprit not the Damsel. Pseudochromis' are a small fish with a big temper and attitude, IMO! If you are going to add more fish, then you may want to put off adding the Pseudochromis till the end!

 

+1 the dottyback will soon be terrorizing your other inhabitants.

 

Throw a trigger in there, that should tame the other fish (and eat them too).... joking!!!

 

i agree with tgood or put something in there thats bigger than the damsel or better yet try to eat the damsel.

 

well i have all aggresssive fish the clowns are bigger than the damsel and wil be bigger than the dotty back. i have to small of a tank and i also have corals to have a trigger any other fish suggestions

 

could i do a midas blenny first then add the dotty back

 

any suggestions
