Ich?

[chucko]

Fairly large white lump where blue meets yellow. I dont remember seeing it a couple of days ago. Little guy seems fine - no scratching or fast breating, eating and behaving normally.

hard to tell, just keep an eye on it. glad its eating/behaving well

that looks like lymphocystis to me. nothing to worry about. just keep up with good diet and water quality and it'll go away on its own.

I agree, its way too big to be ich. Ich is about the size of a salt grain.

Its definitely bigger than a grain of salt. I can see it from the top - meaning its not really flat but more round. Ive not really noticed any other symptoms either.

I don't say "definitely" with pics too often, but this is defiantly not ich, it has way too big. I agree wit Sandi54, I'm almost sure its lymphocystis. Google "marine ich' images; you'll get pics of very infected fish, but just look at one spot. Lympho is a virus, some think it flares up with stress. This will almost always disappear with good water, a good diet, and time.
