Tangs in a 90?

This expert has a Zebrasoma in a 38G (its says 40 but he posted that is actually a 38G).

My opinion is that a fishkeeper's dedication and capability is way more important than size of a tank. I had a Hippo in a 38G several times with no problems to the fish and only got rid of them because of the bioload issues. The fish showed no stress nor stunted growth. I sold the first one to somebody with a 200G tank but due to a non-optimal environment in the new tank, the tang didn't make it very long in the new owner's tank.

I suspect that more tangs die in bigger tanks of fishkeepers who didn't know what they were doing than in smaller tanks of fishkeepers who did know what they were doing. In other words, if you know what you are doing, you can keep a tang in a small tank. If you don't know what you are doing, a tang won't survive no matter what the size of tank. Tank size is less important when compared to the fishkeeper's ability.
