What Could Be Causing This?

[Le0n]

Just looking for some ideas really, my fish have been flashing/rubbing on the gravel and plants occasionally.
About 5 or 6 weeks ago they had whitespot which I treated without any fish losses.
Since then they have started flashing and i have treated them with Waterlife sterazin for flukes and worms but this didnt work.
I do regular water changes and my water stats are normal. The fish appear to be happy and healthy otherwise.
Any ideas?

Sometimes they just get an itch. Personally though I'd treat for ich again, just to be on the safe side.

So after a bit of observation, I have discovered my aquarium has Planaria (small hair like wiggly worms) so possibly this is the cause. Apparently they can irritate the gills but are otherwise harmless.
I think they are living in my filter because I saw them coming out of the outflow. Not a lot just 2 or 3 a minute for a short peroid of time. My neons are gobbling them straight up though so I am not too bothered about having them to be honest (free live food )
