My boss's friend had one for about 6 months in a 180 that is METICULOUSLY cared for, and when I say meticulously(sp) I am not joking, this guy is border line anal. But anywho, he had his for 6 months, and all of a sudden got ich, he got rid of the tang, and he also lost 5-6 fish that got ich also. I had one, at one time, and it never ate for me. They are prone to ich and hlle. I would only attempt it if you are experienced w/ years of experience, and have a big enough tank for him 125 gallon plus(minimum 6ft tank).
