Thanks guys, again, only a couple of the 20 SMB I've caught this Winter had those small spots - maybe 2mm diamter, they almost looked like freckles - not raised or inflamed or anything that APPEARS harmful. Thanks for your reassurance Sunil, Scott and Cecil...you know how I feel about my SMB babies. I feel a sense of relief, but will keep you posted via photos on other fish and if it's increasing in frequency, etc.
