Have a scopas and a yellow belly regal in my 75, both of which I've found to be good eaters and resistant to sickness. They REALLY love that garlic seaweed I give them though.
Scopas I got from my local petco while I was in getting some dry goods, more of a compassion buy than anything usually wouldnt get fish there. Was so sick you could see right through him, got it for $10 threw it in the sump and away he went eating all kinds of algae down there, fattened right up. That was about a year ago now.
