Other fish, Yellow Tang, Blue Tang, Purple Tang, Red Hawk, Cinnamon Clown, Clarkii Clown and a couple of Gobies. I did a search last night on the web and found several articles that outlined problems with Yellow Tangs and Niger Triggers. But last night during feeding they were swimming next to each other with out even a glance and it seems like if there was a problem you’d see it during feeding. Any other time I've had fish problems, the one getting beat up was still getting worked over by the bully even after it had surrendered. Hard to get good pics, he's still pretty active, catching him would be almost impossible at this point.
