The males are establishing a territory. It happens. This is the reason why you heavily plant the surface of tanks if you keep Livebearing fish. Attached is a pic of a 45 tall Livebearer tank with a lot of plants on the surface. In this tank there's Hornwort. This way a bullied fish can move up into the plant to hide from the bully. This is also good for fry to escape aggressive adult fish.
Surface plants keep the peace and make the shy fish more comfortable.
Just a suggestion, though.
