Hi to all, I have a 155 gallon bowfront, I do have some mixture of corals. Getting there slowly. My question is that I would really like to add another large fish. I currently have 3 paj cardinals, 1 scotter blenny, 1 midas blenny, 1 firefish, 1 candy hog fish, 1 six line wrasse, 1 exqiste wrasse, 2 clowns and 1- 4 1/2 inch yellow tang, who is aggressive. Whatever I get I assume will need to be larger than the yellow tang, would really like an angel fish. Any ideas?
