On the top pic you can kinda see the gonopodium, an anal fin has a very even look to it when folded up but the gonopodium on this guy is a little more obviously pointy. It seems to have sort of an off-whitish color to it on the fringes also.Its really hard for me to tell, it looks pointy but the person at Petsmart insisted it was female, and to me, I dont see it fanned out. Do these pics help?
