I used to house one in a 40, it was fine for the 4 months it was in there. Baring it mind that this was about 2.5" big. But one day he just died. You'd be lucky to get one that lives past 6 months. I had no other tangs and it wasn't agressive but all the other fish were around the same size. Although it was in a 40 (this was before I knew much about Tangs it was an impulse buy) they need a big tank. They get the same size as the Sohal and have the same nature. So if its for your 60 or 75 then i dont recommend it as they dont live very long, get big and can be vey agressive. I understand this may sound a little hypocrytical as mine was in a 40 but like i say he was very small and I hadn't really researched about Tangs so I didn't know how big it could get and how agressive.
