Your grouper and you trigger will need a tank that size. Make sure they go in your 210. And having a trigger (esp. adults) in a reef tank doesn't always work out. So a FOWLR setup would be nice for it.
hey Mainy999 i hate to bust your balls on here in front of everyone but you are wrong about the Humu Humu......... yes it is the state fish in Hawaii but it is not the Humu picasso:
Both are aggresive fish but the Humu rectangle is about 2" bigger and the Picasso is much prettier.......and also Humu Humu Nuku Nuku A Puaa means: "fish with a pig like nose" And they both grunt.
hey, i just joined as well and i just plumbed my 210 . its going to be a reef tank , i currently have a 55 reef. depending on what you decide to do you could keep your 65 as a refugium.
