So here in lies the confusion.... the description below states that a Pulani Tang is often MISTAKEN for a Dussumier BUT according to iucredlist.org, the Dussumier is also know as the Pulani Tang!! Confused? Me too.
Nevertheless, this is what I've found so far in regards to this;

Description
The
Palani Tang is often cunfused with a Dussumier Tang, but the differences between the two are the coloration and origin. The Palani Tang comes from Hawaii and its coloration is not as bright. The Palani Tang grows to be one of the largest of the Acanthurus family. Because of it’s size and level of activity, it will require a large aquarium and very well oxygenated water. Both the juvenile and adults display beautiful coloration. Often purchased to assist in algae control, Dussumier Tangs will spend their day picking at rockwork and occasionally sand in search for hair algae to eat.
Diet
In the wild, Tangs spend their entire day swimming around on the reef in search of marine algae and meaty bits of food they can find. If underfed, it is often noted that tangs will likely pick at large polyp stony corals. It is recommended to feed dried marine algae (Nori), Spirulina Flakes, and frozen mysis shrimp. Tangs quite easily adjust to captive diets and will eventually eat flake and pellet foods as well. It is recommended to soak flake food in some type of vitamin supplement like Selcon or a garlic supplement in order to help the fish fight off any possible parasite infestation and offer balanced nutrition.
