Ishrana: as with all Tangs they graze on algae all day long. if there is not a lot of algae in the tank you must supplement vegetable matter. I recommend Nori, the stuff sushi is wrapped in. it is available at any good oriental food store. you can use spinach or romaine lettuce but this is not a natural food for them and should only be used every once and a while. they will also eat brine shrimp which should ocasionally be fed to them. other frozen and flake foods are o.k. for filler, but nothing more.
Ponašanje: purple tangs are good communtiy fish and have a good temperment. However they are aggresive to other tangs, as are all other tangs.
