It was amazingly easy. We have been watching a white spot (not ich) on the tail of one of my Bass and last night I noticed something seemed to leach out from the spot on top of the skin and looked like it was about to fall off. So after preparing for a struggle with a floppy fish, we netted him and layed him on a towel (still in the net) and used a non metalic object to scrape it off being carefull not to remove too much slime and scale. He didnt flop at all and the whole thing took less than a minute including dabbing some Pimafix on the site. He didnt look too bad last night and he looks totally normal today 
Hope he does ok.
