Hi...
two of my discus, the pigeon and the blue diamond changed their patterns. The lines/stripes of the pigeon have turned into dots and, the blue diamond now have firm dark frame on both above and low fins. I really wish to be able to attach their recent images on this message so that you'll have your own opinion about what I mean.
Anyway, any responds will be much appreciated...oooops and my question is : Are they normal?

Thanks a lot for your answer.
