I started my 150 gallon tank about 2 months ago. Tomini Tang, Yellow Tang Naso Tang, and Sailfin are my first fish. They all get alone fine. However, I added a Blue Jaw Trigger, Flame Angle, Coral Beauty, Lemon Peal, Half Black Angel, and Elibi Angel last week. My Tomini is only 2 inches, but he bullied every single new fish including the Trigger. Within 24 hours, my new Elibi was killed. What can I do to stop his aggression can stop?
