I bought this little guy / gal a few months ago along with a few others from the typical grab bag unsexed juvenile Peacock tank. I scored pretty well. Apparently all males, and coloring up nicely. This fish was noticably different. Thinking it was a baby Red Empress mistakenly thrown into the mix, I bought it. Since then, it has developed a sulphur stripe spanning from head to tail and it's face is turning blue. It is also getting a thick blocky shape. I'm normally pretty good at fish identification, but this one has me at a loss.
