I have one (going on 6 years),with 3 other tangs(saifin and two yellows) in a 180g.
Can't say that this is my most aggressive tang and I have no horror stories.
Hope you quarantine him as they are prone to ich...I did mine with copper.(Tried hypo but that just never seemed to work for me.)
Room may become an issue as mine swims the 6 ft length of my tank all the time and my tank is double sided (rocks in the middle).
Good luck!!!
From your post I'm gathering you have some sort of large tank project coming up? Clown tangs are pretty common...I see no reason to "bite the bullet" now.
I was also at the Baltimore Aquarium last year and noticed they had 2 clown tangs in a very, very, large reef tank. These guys get sick big, and are listed as an expert only fish.
I consider myself a pretty decent fish keeper, but after losing my Achilles tang that had been doing great for almost 2 years, I won't try a difficult and problem prone fish again...no matter how beautiful.
You can see here in the Greenwich Aquarium Reef Tank that it's the only tang in the tank I believe....and it seems like this tank is 8 feet long and at least 4 feet front to back, roughly 500 or so gallons.

. Also I would like these post to be a negative free... I don't need anymore horror stories,.
The responses aren't negative, and there are horror stories for a reason. A clown tang in a 120 gallon tank with 2 other tangs is a bad idea from everything I have ever read and heard about these fish.
I'm pretty sure I said no one said anything negative. I don't think I asked why there were horror stories either, not to be jerk.:thumbsup:
