I did however add a few more rocks today to try and create more spots for them to claim their territories.
You forgot to include the size of the aquarium. Off the top of my head, you have a lot of aggressive fish in this aquarium (a lot) and all will be attempting to establish their own territory (as all are very territorial fish, except plecos). If you do not have adequate land scape for them to call "home" then that tank is simply a time bomb waiting to blow, this could all very well be caused by tank size too. But you would need to include the tank size for this to be determined.
When I mean you need adequate "landscape", I mean you must have dozens of caves and places for them to call "home".
