Does anyone know how to sex common plecos? I was finding mixed results when I searched on the interenet and was hoping that someone here would know how to tell the difference.

Well!
Beside having a look at the genital papillia, there is no other trick to sex with 100% chance one of those common pl*co species!!

Well, I was afraid that would be the answer. Are there any good pics of what either sex would look like? I have never vent sexed pl*cos before. Would it be like vent sexing a syno?
