I would say TSA’s photo which was posted earlier is accurate in contrast to my King Jester which I managed to witness spawning in my tank as shown below.
Jesters are definitely an indo gold variant, perhaps one of the nicest imo. As for the Joker, I’ve found a significant amount of different variants of it circulating. I have one with a neon green mouth, purple arms and pink tips. I’ve seen yellow tips as well which looks really nice but more difficult to come across.
