Film Algae and Fish Stress?

[showey472]

Recently I have noticed some behavior changes in my fish when the algae starts to build up on the glass. I have 2 Chromis and 1 Clownfish and I noticed that about 10 minutes or so after I clean the glass and for the next few days they will pretty much swim in all areas of the tank. But when the algae starts to grow on the glass the Chromis hide in the rocks and the Clownfish stays in the back corner at the bottom of the tank. Was wondering if any one else has seen these kind of responses in their fish and if having the algae there is causing extra stress on the fish?
