About the best thing you could do is try to eliminate sight lines with lots of plants or decorations but even if it works it will be a short-term fix at best.
Red Devils are one of the most aggressive/territorial fish you are likely to find. I would say a single Red Devil would need a 75g tank.
How the Ich doing?
I do see any white flake on them but I still keep the water temperature at 86 and still doing water change I did put some salt in the tank last week when they where duping in the tank
