The guy I her from had her for abour yrs and I have had her about the same time. So about 6 yrs in tanks. She is by far from favorite fish. I would take her over any fish I own, goldflake, black tang anything. Put it this way, when I had my 220 up and the tangs outgrew it I was going to sell everything. I couldnt think of getting rid of my orange shoulder. So the 450 went up. thats how awesome of a fish she is!!!
