Fish thrusting their sides into rocks or decorations...

A couple of my fish do this now and then like they are trying to scratch or something. Or are they playing? What I mean is: They very quickly accelerate the side of their bodies into a hard surface.

See tank blurb for tank info.
Set up for about 10 weeks.
No live plants.
Eheim Classic 2213 filter.
No direct sunlight. Darker room.
Water changes: 2 every 3 weeks. Bout 30%.
Feed once a day.
All test are very good.
Recently lost my first 2 fish: a rosey barb and a black platy, but they hadn't been doing this "scratching" thing.

This action is known as "flashing" and is common behavior to most fish. It must be mentioned here, though, that this action may also be an indicator of a dermal problem such as parasites or other malady such as poor water quality. A check of the water quality using a quality test kit (check for ammonia, pH, and nitrates) as well as a more than casual inspection of the fish will determine if the "flashing" is normal behavior or a problem that needs to be addressed.

Yeah, I agree, flashing is often times a sign of possible ich...even if you don't see white dots. I would test water perameters and do any needed water changes to make sure that water quality is good. I would also suggest temporary use of freshwater aquarium salt and regular use of a stress coat. You may have cought a possible illness early on and these simple procedures could prevent something more serious. Keep a close eye on any physical irregularities on the fish.
