I have a 120 gallon fish/reef tank. It has been set up for about 6 years. Currently have 2 false purcula clowns, 1 banner cardinal, 1 six line wrasse, 1 flame angle, cleaner crew and plenty of coral. I want to add some new fish but I am unsure what I can add. I would like to add a blue hippo tang, a yellow wrasse and a mccosker's flasher wrasse. Would they be ok?
