Jing kang juvie looks like an ordinary fh until they go through a molting process. I have not been able to tell the difference.
A fader is not necesserily a Jing Kang, but we often assoc. fader to JG like a red devil or midas going through the molting phase. If a fader molt into red and yellow, then its a jg, base on the original color of JG.
It's been so long, but I think a fader can become a red shock too. Its been years since I kept red shock so my memory is blurry.
