flukes maybe. Ich in the gills maybe. Can you possibly lay fish out very briefly on non-grippy surface and get a strongly magnified look into the gill? Rough on the fish, but if you spot a jellylike thing it's a fluke and if you can't see anything it still could be ich...or velvet. Hard call. But if you can eliminate flukes as a possibility, you can treat with copper, which would get either velvet or ich. If you can't do that, I'd still just about bet on copper, because two things that are possibly wrong outnumber the one other thing it could be, and it would be a better shot at curing two possibilities with one treatment.
NOTE: There have been flukes turning up in CA. You don't say where you are.
CAUTION: you cannot combine treatments. You must slowly bring the fish out of hypo, like an acclimation, before attempting copper. And it must be done without carbon in the filter: the black side of those little filter packets is carbon.
