I bought two small Tank-Raised false perc clowns. when i got them, they were both pretty much the same color (bright orange). I am noticing that now one of them has gotten a little darker and has more black on him while the other is still bright with less black.
Could this change in color be due to it changing sex to be a pair? how do i know? and if so, which is the male which is the femals? (they are still pretty much the same size).
