Good to hear.
Territorial behavior is directed at conspecifics. They are not guarding a nest from any and all fish. They are fighting for their territory with the same species. The presence of other fish in the tank may or may not have any effect. If it does, the effect will be weak. The main factor is space. If the bigger one decides the WHOLE tank is his territory, he will always bully and chase the smaller one.
