Behavior:  The Sailfin Tang is one of the most personable fish you can find.  They are extremely smart, and are fun to have in your aquarium. This species is normally peaceful, although larger specimens can be aggressive. Further, aggression may occur with other tang species. 

Feeding and diet:  Must receive a diet rich in vegetable matter. Provide a varied diet, mostly of vegetable matter.  Feed dried and frozen herbivore  foods that contain marine algae and the blue-green algae Spirlina. Supplement with dried green algae stripes daily. This species will accept a variety of prepared foods, but special  care should be taken in providing it with a good deal of green algae

Reef Compatibility:  The Sailfin Tang makes an excellent marine reef aquarium fish since it will graze on macro algae and other green algae, but will leave the invertebrates alone. If underfed may nip at corals.

Cautions:  Like most fish in the Tang Family, they are a fish that do not play well with other Sailfin Tangs.  They are  very territorial,  so if you put two of them together they will fight.  Because of the razor/spur by the tail, when  they fight they will cut each other up.  It is not advised  putting more than one to a tank.
