They are very active Fish that will make the whole tank his territory, If healthy when purchased chances of survival increase, they are a magnet for Ich and require a large tank 225+ gal with a lot of flow. Love to swim against water stream. Once recognice the owner they behave like a pet trying to please.
Recomend the presence of cleaner shrimp, feeding nory and garlic plus various fresh fleshy and flake foods. Also require pristine water conditions in a very stable tank.
Will flash and dominate any other tangs. Usually will not bother other species.
