Sexing Gastromyzon Punctulatus

I was reading an article on loaches on-line (http://www.loaches.com/baby_cheni.shtml) by Roxie Fredrickson about breeding Pseudogastromyzon Cheni. It mentioned that they can be sexed by snout shape and protuberances on the side of the snout.

I was wondering if I can tell what sex my Punctulatus are? All three have rounded snouts. Two are larger and darker with little whiskers at the front of the snout. They are more agressive. One is smaller, lighter and less well endowed in the whisker department.
