Proportions can only be used to compare very similar sized fish. In fact, a 14" Sailfin Tang wouldn't be particularly happy in a tank that is any smaller than 240g (some people would argue this), and that is over 17x the length of the fish and 0.05" per gallon.

By proportions I meant ideal swimming lengths compared to tank length.... which is not necessarily related to fish size or your 1/2" per gallon relation which is not at all what I meant by "proportions".
But you kind of made my point for me... how much swimming room do tangs ideally need and what size of tanks are they often crammed in? Looks like a lot of people have no problem putting them in a 4' tank from a recent thread

but you say ideally some should be in 8' tanks.
So yeah Big Als tank isn't ideal and it would be nice if it was twice as long but at the end of the day they're just doing the same thing that 95% of other people in the hobby are doing.
I'm not saying it's the best thing in the world but it just part of the hobby. You want something but maybe you don't want to have a tank that big.... so you push the limits.
