all male peacock cichlid tank question

[LilBabyEmma]

im working on a 55g all male peacock cichlid tank atm i have 4 fish in it
my red shoulder picks on my albino ruby. i was wondering if i just set some rocks in the tank without making caves if it would help the agg

Anything that can disrupt line of sight between the aggressor and the victim will help. Any pictures of your tank??

If you dont have any decor in your tank then yes, rocks will help even if there are no caves. You need to hurry up and get more fish in there!
