Generally a good sign that it is more than likely ick.
I would slowly raise the temperature to 86°F (by slow, I mean 1-2 degrees per hour), start salt treatment immediately.
You will need aquarium salt, NOT table salt or marine salt, adding 2-3 tablespoons per 5 gallons of tank water. Maintain the salt treatment for at LEAST 10 days, DO NOT stop treatment once the spots start disappearing off the fish, you need to keep the treatment going.
The fact that your fish are not displaying the "salt like" stage yet, but are rubbing on things, is more than likely an indication that the parasite is taking hold and annoying them.
Before adding the salt, perform a water change and vacuum your tank, this will help remove any free floating tomots (the swimming stage of the ich lifecycle).
If you need any more information, please do not hesitate to ask.
