YEs, fans seem to do the trick for me in my vertical tanks. All I have is screen opening at the top of the viv with a fan on one side. Air I suppose comes in at the bottom of the tank through small gaps between glass plates. And I have the fans blowing air out. This keeps the front glass fog free even without the fan on.
