Purple Tang - Beautiful, tough and great personality. Been rooming with it for ~2yrs. now. It recently decided that my 100 reef was too small for it and the Kole Tang, but it's otherwise been a great fish. It's grown so much in two years and is now healthy, plump and hopefully happy. IMOHO, they're the heartiest Tangs.
Majestic Angel - Just introduced one to my med tank (58 gall FOWLR). I've heard they're delicate, so I'm hoping for the best. It's sharing this tank with a Med. Yellow tang, two Percs, a Wrasse and a Seahorse. Everybody elso in the tank has been getting along nicely for quite some time. The Tank is full of Caulerpa, so even the Seahorse gets along. I know this is a wierd setup, but it seems to work... I just hope the Majestic doesn't upset the balance. So far (7-9 mos.) Nitrates are 0 (caulerpa rocks!). I'm setting up a refugium this weekend to offset the bio-load of the Majestic, especially since it seems to love eating caulerpa.
I'm crosing my fingers and hoping the Majestic pulls through... Re: the title of this post, I'm still a little partial to the P-Tang.
