In nature most cichlids defend an area of between 4ft x 4 ft x 4ft to 6 x 6 x 6.
And though depth isn't quite that important, foot print is. So even a 220 gallon, is small compared to the kind of territory a mature alpha cichlid holds in nature.
With my festae in a 6 ft tank, I always provided a divided section where the females could get thru and escape a dominant male, but would block the passage of that male. Although not aesthetically pleasing, I found it was the only way to keep females from being killed, or stressed into disease.

The female in the pic above and below is about 5".
