There is never going to be a consensus for Tangs. Most sites will say 120-180 for the larger Tangs. Smaller bristle tooth types (kole, etc) are probably okay in 75-90. There will always be stories (as we already have in this thread) of a Regal or Yellow tang living for years in smaller. My question would be "Did it grow to the size, a foot, that it should have?". If not, then we have stunted growth, which can't be good. I know someone with five Koi in a 35 and they have been in there for seven years. They should be in a pond of probably 750-1000 gallons. Target are nowhere near as large as they should be, but appear healthy.
I tend to agree with the 6' rule for larger Tangs. I just don't see it being good having a fish that should get up to a foot long in a tank that is that deep/wide. Just because they might live, doesn't mean it is good for them. There are so many great choices in saltwater, I can always find something else that works and makes me happy.
