I find it wierd that the sevs don't bother the gouramis at all. The only fighting I have is between the two gold sevs. I rearranged the tank and everything when I added him. When they aren't close to each other they are fine. But the the smaller one always swims over to the bigger one. Fish are wierd but beautiful lol
This tank looks fairly new from photo, and if so,, I would not be in too big a hurry to stock it with more than one or two fish at a time with week to ten day's between additions.
This will allow biological filter to adjust to increase in waste produced by the fish.
Cichlids will establish pecking order and this could take a few day's to a week maybe.
Until this happens it is common for them to pick on smaller fish or new fish to establish dominance or territory.
Would add more decor in the way of larger Driftwood pieces ,more plant's either real,or artificial, and perhaps some smooth stones (check landscaping stores).
As mentioned above,,, ONE blue Acara, or ONE Firemouth,or ONE convict would be safe with regards to stocking level and compatibility keeping in mind Adult size that fishes can achieve with proper care.
Should never be about how many fish can we fit in a tank.
