I've had mine for about 5 years. They are beautiful. But be warned: they are ich magnets (they will be the first fish to come down with ich should something happen) and after they settle in - they will rule the tank. I can not have any other tangs, or fish close to his size, or fish shapped like him. I probably should have added him last! But they are truly awesome fish. Make sure you feed lots of vegetable based food - this fish must have his vegies. Dried seaweed every few days will be much appreciated.
