African Cichlids urgent help?

I have three frontosa in with other fish in an 125 gallon tank. The bigger Frontosa is always chasing the other two around the tank constantly, where these frontosa are hiding in the corners at times. However when I tried removing him the other frontosa just took his place and started chasing the second one. What do I do? I have a total of 12 fish a mix of peacock cichlids, haps, and frontosa. There are plenty of rocks, and hiding places. Is it anything to do with food, I feed my fish once every other day?

1. Normal
2. Sometimes additional decorations, breaking up the territories, helps
3. Additional water flow, more turbulence
4. Good luck though, because adult fish are much less tolerant of others and this gets worse at breeding age.
5. If you had another tank you could buy 20 tiger barbs and grow them up to be bigger than a mouth full and add them to the tank as "chew toys", known as "dither fish" . (I know, no time for that, but large tetras, like large silver dollars, or other large barbs would work)

Note: calculate your total water flow, you're looking for up to 10-15 times the tank volume in flow from all your pumps/filters.
