I’ve had a 125gal for 3 years now. Currently have a 3 inch hippo tang, royal gramma, longnose hawkfish, 2 clowns(don’t know what type they look the same to me), midas Blenny, mandarin and chromie. I’ve tried to add fire fish, Banggai cardinal, Anthias and other pretty laid back fish. The problem is they get picked on and eventually killed or had to rehome new additions. Am I at a point where I need to add aggressive fish so they can hold their own against the current bullies? Any suggestions on new additions
