Breaking the sight line in aquariums

[_Carla_]

How do you all break up the line of sight for fish that might be aggressive?
I had thought maybe floating plants that sort of thing. I have 6 Scarlet Badis coming and I expect all males. I hope they won't go after each other. My tank is taller than wide so maybe some tall wood would work?

I use wood, rocks & plants but I've never had more than 1 badis, they sem to be more bottom-mid water fish AFAIR.

Well that will be good because it's planted heavily. I thought I would find some water wisteria to fill in the top. It can float and not have to be planted in the substrate?
