I was thinking of adding a blue hippo tang to my 38 gal. This site says min. tank size of 40 gal. But I see tangs in reef tanks all the time that are supposed to be under the minimum. Here is a link to a photo contest that has a yellow tang in a 29gal.

So whats the deal?
Please don't do this. For one thing, the minimum of 40g would be to hold a juvenile temporarily. You certainly can't keep one for it's entire life in there. Some will even say it will outgrow a 90g tank. Keep in mind 2 things:
1. Hippo tangs will grow to be 12 inches long. If they don't, they aren't healthy. I have seen them this long in numerous tanks. It does take a few years to reach that size, but in order for it to grow properly it needs adequate space, and a 38g certainly isn't adequate.
2. In the wild, this fish is an active swimmer. It will pace back and forth in even the largest of tanks. I have one in a 180g and sometimes it doesn't seem like enough length, but it can definitely live a full and active life in there. Personally, because of how active they are, I wouldn't recommend anything less than 125+ gallons for long term housing, but again, some people try them in 90g. The length thing is an issue there, since it can grow to be 1/4 the length of the tank.
Hope that helps, and please, again, don't try to keep one in such a small tank. They're prone to numerous ailments when they get stressed by their environment.
