Just to add, the reflections we see when we look in a bare bottom tank, aren't seen by fish, they just see the white styrofoam underneath the tank.
I use barebottom for my goldfish, but in my cichlid tank one side has a thin layer of gravel, the other side has large smooth river pebbles, makes it so much easier to clean.
