Just remember humidity is the most important thing, red eyes will turn to prunes before moving 20cm to a pool of water, so limited ventilation and a damp, warm, clean substrate.
My tank is one of those... uh forgot the brand. umm it has like sliding doors, plastic outlined mesh lid, and ventilation on each side, would you suggest blocking of almost all of that? or just the top or sides?
not the best tank for them, red eyes get out through small gaps and sliding doors have small gaps. you really need very limited ventilation, so that the sides of the tank are wet.
