It sounds very like the peppering you get with pigeon blood type discus. However, am pretty sure you don't get this with wild strains.
Are they scratching or showing any symptoms of parasites?

Hi there,

We need a picture, as mentioned it could be peppering which is sometimes seen in domestic strains but there are a number of other things it could be.
