Jeez....my experince is almost identical to Marine Fanatic! Not my first fish, but after the tank was 6 months old was when I got mine. And mine came down with ich, and after several attempts to clear him up, I ended up destroying him. No other fish had ich before, during or after him.
I later learned that my running carbon in the filter might have been stripping his slime coat, so if you do decide to get one, leave the carbon out!
And yes, a very nice peaceful fish. The only drawback (personality wise) was that he would pick at my christmas tree worms.
