The fish is a foot long. I don't think it would be comfortable in anything smaller than a 180. Even the 120 I'm working on wouldn't be big enough.
Did you sell all your corals and rock already?
I'm interested... I have a 220. What fish do you have him with? Sorry for all of the questions but I wonder if yours could live with my fish. I have a grouper and 2 tangs that are pretty aggressive with new fish.
