I have an albino which I believe to be male and a regular which I think is female. I will be attempting breeding so I wanted to make sure I have one of each sex. First two are the regular (female?) the second two are the albino (male?). Both are about the same size, close to 2"

albino is definitely a male. as for the regular one, it is hard to tell, as there are some small bristles along the edge of the snout, and sometimes females will have a smidgen of bristles, but sometimes they don't. i have a full grown female bristlenose and she has always been completely devoid of any bristles along the snout edge (either that or she secretly waxes her fishy lip for her pleco hubby, hahahahaha!)

The pics are fine as they are, it's just a matter of the fact that they're still only 2" long, and their bristles aren't fully developed. So sexing them based on their bristles, is sketchy at best (aside from obvious males with lots of mid head whisker growth).

Right now, I would say regular female, albino male. But 6 months from now, the supposed female may very well get a bushier mustache of her own and turn out to be male after all.

I had a regular bristlenose which I purchased from the LFS as a "female", that was about 2" long. That was around 8 months ago. "She" is now a "he", with a nice bushy nose that puts my old 5" male bristlenose to shame!
