For Wrasses, IMO you will want to definitely remove the Whipfin (C. filamentosus[FONT=verdana, geneva, lucida, lucida grande, arial, helvetica, sans-serif]) & Red Velvet (C. rubrisquamis). Longfin (C. rubriventralis) is another that is questionable. Other are all ok, except confirm the scientific name for the "Christmas" Wrasse". You want H. claudia, not H. ornatissimus. Here is some more reading on reef safe wrasses for you: [/FONT]All About Reef Safe Wrasses - 3reef Reef Aquarium Forumangs - I am not an expert by any means, but here are my thoughts:
· Blue Tang - Ok.
· Blonde Naso Tang - These really are borderline for a 180. They should really be in an 8' tank minimum IMO.
· Purple Tang - Ok, but I would recommend only one Zebrasoma.
· Yellow Tang - Same as Purple; You may get lucky; you may not.
· Red Sea Sailfin Tang - Again, same as Purple & Yellow. And also borderline on the size (although the Red Sea variants stay a bit smaller IIRC) and also can be more on the aggressive side IIRC.
· Orangeshoulder Tang - Ok
· Powder Brown Tang -Ok, mixed reports on how aggressive they are with other tangs. I myself am adding one along with a Kole Tang to my 125.
· Atlantic Blue Tang - Not as hardy as most other tangs from what I know, but otherwise should be fine.
Finally, Pipefish belong in species tanks, not in mixed reefs IMO. Care is very similar to Seahorses.
