Fading/peeling is a hybrid crap term....sorry I had to, so to answer your question Cyanoguttatus or carpintis do not unless they are hybrids, both fish I would be weary buying from a lfs and expect either species...
I answered his question already and fading is not a hybrid term... It's an amphilophus term. I agree about buying from an lfs because they can look pure and still be hybrid as Onefowl1 mentioned earlier.
