Salt your tank (1 tablespoon per 2 gallons) and raise the temperature to 80 degrees (gradually). Keep this way for a week to 10 days. You will need to do water changes to remove the salt once complete. This method worked for me.
I think the cherry shrimp will be okay with the salt & temp from what I've heard- but you should double check on that. Otherwise, you will have to use ich meds.
