    Just wondering if only male Plecos do gill flares because I’ve been trying to sex my little Bristlenose but it’s so small it’s really hard, but today he flared his gill spikes so he might be a male right. Correct me if I’m wrong

    I found this on AquatiMag.com;
    Sexing Bristlenose Plecos
    It is very easy to sex. The male bears more bristles at the center of the head whereas the female bears less number of bristles than male around the edge of the chin. The male also possess well-developed odontodes on the pectoral fins and opercle while the female does not.

    Ah. I don't really know in that case. I'd just wait it out until he grows a bit more and sex him then.

    All bristlenose have the "cheek" spikes, they are a defense, not a way to sex them.
