As most of you know, I just purchased a Marineland Portrait aquarium for my betta. As I have mentioned in previous post, it has a black plastic wall which hides filter/pump. I have difficulty locating my black betta in it. So below are pics of original tank and pic with white craft canvas against back. I need holes for water flow. I know the white doesn’t look as flashy but do you think it will do with more tall plants in the back? Any other ideas? The black plastic divider wall is not removable.
