Rainbowfish and salt?

[Lady Hobbs]

I have thought for some time of setting up a rainbowfish tank but often I read they need salt added to their water. I wanted to keep them with my Silver Dollars who do not like salt. Does anyone know if rainbows need salt added and if it's all varieties of rainbows? I'm been trying to get this information from the net and some species say salt is definately needed but other species this is not mentioned one way or another.

I have a 120 rainbow show tank. I dont use salt and have not had a problem
