With all due respect, your tank's decor is not realy enough to house multiple territorial fishes. (IME: in my experience) To house multiple pairs of clowns I would put enough rock in the middle of your tank to almost split the tank in half. Build it up in the middle so that the 2 pairs could live without seeing each other if at all possible. Make sure that there is adequate water circulation through the section by either adding an airstone or power head to force water through the divider so that there are no dead spots of water movement.
Don't be shy about putting more decor. Below are 2 pics of my old 75 gal
tank. The one with the fish in it was taken 10 minutes before the lights went out. (Unfortunately, you can't really see all that is in there but if you look hard, you can see the face of my juv. majestic angel in the dark hole to the left of the staghorn coral above the red pipe organ coral and my med Blueface Angel was already behind the montipora coral on the right bottom of the tank. ) You'll see a spray bar on the top left which circulated the water across the top half of the tank and there was a power head buried from view (but accessible from above) behind the big mound of coral to make sure there was circulation through there. The base decore was lava rock set up so that there were a myriad of tunnels and channels for the fish to swim through and the water to circulate.
The second pic was taken 10 minutes after lights out. As you can see, by having all these areas for the fish to feel secure, they were always out in front when the lights were on. All my tanks have been set up as the "edge of a reef" so that there was room for swimmers and homes for territories. In this tank, I had 3 ocellaris clowns ( on the left) and a pair of Pink skunks that would stay in the bottom right side of the tank. They rarely saw the Ocellaris except at feeding so fighting was almost non existant.
Now, before I get grief from anyone about the natural corals in my tanks as decorations, know that these corals have been in my collections for over 30 years and have been out of the water even longer. Please don't send PETA or any Government agencies my way because these were all legally collected at the time.
By the way: by keeping all this natural coral in the tanks, I never had PH or alkalinity probs because if the levels fell, the coral would "dissolve" and bring the levels right back up. Just like in nature
