Do the salt treatment just in case. Some protozoals will cause this as will ich, the protozoals are to small to see.
 
Fish can get itches, and do this to relieve themselfs.. However, if they do it all on a constant basis, it can be trouble. It's not a completely normal behavior, when being done often. What are your water paramaters? Extended periods of high nitrates I have noticed will cause this too..
