Gee like this has never been posted. But currently I have a 180 with very few fish, which is why I'm a bit apprehensive. About the only ones out swimming are a purple and naso tang, a copper banded butterfly, and a fairy wrasse. I'd love to add a power blue tang. I just upgraded from a 120 to a 180 2 weeks ago and I should have added the PB when I moved the tank over, but the purple has had 2 weeks to get territorial (as of now the naso is a wimp and let's the purple run things). Even with the bigger tank, will the fact that there is so few fish be a worry? It's not like they won't run into each other; the 3 tangs and a couple other fish will be about it. Thoughts and other tang suggestions? thanks!
