Definately no, you might put corals in, and all will seem fine. Then out've the blue you see them being chewed on. Softies and all are not safe especially triggers with the perfect snouts and mouth for nibbling, and getting into crevices like the Bursa. My Hummu never touched the 1 softy I'd had left in my tank for months. Then one night the wife and I were admiring how much it'd grown in a tank with messy fish. No sooner than the words came out my mouth our Hummu grabbed it swam straight backwards, and shook his head like a pit-bull on a piece of meat.
