Hi everyone, I am a new member looking for advice. I was wondering if anyone could advise about adding angels into a reef tank. I have a 150 with a naso, powder blue, and 3 yellow tangs. Also copperbanded BF, mandarin goby and cleaner shrimp. For corals, star polyps, zoos, mushrooms, ricordias, toadstool and brain coral. I have seen others with blue faced, blue girdled, emperor and flame angels. Do they work, or will the angels pick at the corals. I was also thinking of adding clams at some point. Please advise.
