Hello all. I'm new to the forum so not sure if posting in the right place... I have a 100 gallon FOWLR aquarium that has been set up for close to a year now. I currently have a yellow tail damsel, royal gramma, valentinI puffer and Niger Trigger. A few days ago I added a Coral Beauty Angelfish and was fine the first few days but it has now started to chase my Niger Trigger. is there anything I can do to stop this?
