Male or Female (Peppered and Julii)

I think the top ones a girl, and the bottom ones a boy. just a rough guess.
 
Hello,

The top one I'm pretty sure is a female, but the bottom one I'm not sure about. If I had to guess I would say its a female. Male Peppered Cories have a longer more pointed dorsal fin then the females. By the way, I'm pretty sure that your Julii is a Three-Striped Corydoras. I bought some so called Juliis from the petstore, but when I got them home I realized they were Three-Striped Cordoras(Corydoras Trilineatus). When you see the so called Juliis for sale, theres a 95% percent chance that they are the Three-Striped!

Don't know on the Julii, but the Peppered looks male. My female has a much shorter dorsal fin spike. Any chance you can get a pic of the two anal fins on it? I find my female has rounded fins (like your Julii), while the males have longer more pointed fins.
 
Sorry they're the best pics I have.

Thanks, I know what to look for now.
Man I was so sure it was a julii, I'll take your word its a Corydoras Trilineatus though. It doesn't really make much difference to me I think they're all cute :).
