Just curious, and sorry if it's been asked before. I couldn't find the answer anywhere else on here. Do most midas (or RD for that matter) change color as they mature? I would venture a guess that the barred midas might not, but what about the orange/yellow/white ones? Also, when you get the RD/midas hybrids from stores, what are the odds they will end up with that nice thick, chunky midas body? In the future, I may be interested in either a barred or white one, but can you tell when they are young at all? Thanks!
