Tank Turned Into War Zone

[jake135]

Looking for a little advice here as my 135 gallon Malawi Peacock/Hap tank has exploded into a brawl that I haven’t been able to control. 3 fish in hospital tank with wounds behind their Gill plates healing. But fish that remain are still going at it. Usually it’s one guy and I can remove him to restore peace, but this seems to be from all sides. Any experts out there have some ideas?

Break up sight lines in the tank using rocks and fake plants.  Allow plenty of hiding spots.  If the tank is open, the fish fight for the entire territory.

Appreciate the response, feel like I’ve got a lot of structure already, but probably have room to go more vertical to break up sight lines further

could be a fight for the females

you breeding or just a display tank?

Just display tank, shouldn’t be a female issue. I took all the fish out did a massive restructuring and water change and put them back in and it seems to have helped just enough to avoid catastrophic injuries . Still have some torn fins but it’s better than it was
