It's agreesive in that it's polyps will expand out to more than twice their normal size and will sting and kill other corals. Make sure you have it far enough away from any other coral . They are a great LPS to have and easy to care for. also mine has now become the home of my false perc who now never leaves the hammer corals polyps and evening spends the night within the branches of the hammer after the polyps have retracted
