Rusty swimming in vertical circles

My yellow cichlid is swimming in vertical circles against the side glass. He is slightly larger than the 9 other cichlids, all about 1.5". They are in color pairs. I had the water tested and all chemical levels are perfect. He eats fine. Is more aggressive than I would like, but everything else seems normal. Has only displayed this behavior for a week.
