Since no one has asked, I'll ask the obvious question.
Why do you want to add salt?
And what kind of cichlids?
The reason I ask, is because I never add salt unless I'm treating for something.

The reason I ask, is because I never add salt unless I'm treating for something, or the cichlids I have are brackish types, such as Etroplus suratensus, or Alcolapia sp.
Salt may or may not help if this is an infectious or fungal issue, and it should be tolerated by Guianacara, even though they seem to be a strictly fresh water species.
But are you saying most of the fish don't have dorsal fins?
