    Default Bristle Nose, Thin spikes vs forked spikes?

    0 Not allowed!
    So I've had these two BN's for this last year. They appear to be in the 4" range and have developed nicely. Both have great personalities and from the beginning I've enjoyed them growing.

    Well come time to sex, it was apparent at that time judging by their faces I have one of each. Well, I'm not really completely sold on that anymore. (for all intents of purpose will call them male and female until told differently)

    Their faces are still very different, but the one I called the female has developed spikes on her face as well. And these spikes are actually longer than the male's. They go all the way up to the eyes and follow the lip line. Long-curvy-thin spikes. However the male has developed thicker, shorter, and forked spikes going all the way to the eyes and along the lip line (ones on the lip line appear reg. spikes).

    Behavior wise, I have this nice burly piece of driftwood that forms an Arc on the bottom of the tank, with a floor as well. I've often noticed the pair hanging about this and ripping their share of wood for their diet... no biggie and good snacking. Well I've also noted them burrowing under the floor of this piece of wood as well.

    This got me psyched!!! Was thinking here we go!!!
    Well, I see what I think is them going through the motions, but no wrigglers.
    I've noted very often though, other species like hanging out near the Burrow, appearing to be snacking. Well, if I have both sexes of BN and mating is going on, then the guilty snackers will be getting the boot really soon!!! Their specie is becoming jaded in my eyes for their already vicious appetite and massive breeding program. (No worries, I'm humane and their only being rehomed to my LFS soon--when I get up the time to do so)

    Anyways, what do you all think? Do I Got a pair or 2 of a kind?

    I'm really unhappy with these pics, but it's the best I could manage with what I had for a camera at this time. Like I said, their skittish ones today.

    Possible Male?

    The burrow is under the bottom woody part, in the dark black part of the pic.

    My understanding is that females have either no bristles or only short bristles around the sides of the mouth, not bristles going up the face, and certainly not long ones like both of yours are showing. So as far as my understanding goes, you have two males.

    +1 Yep, Although it's really hard to see in the one pic due to the leaf.

    Also they like to spawn in REALLY tight places so don't expect any cave to do the job. I have a pleco cave in my 90 and I think it is far too big because I have literally never seen them in it.
    Gas mileage isn't everything OIIIIIIIO
    Lack of planning on your part does not constitute an emergency on my part.
    Why pretend there are no stupid questions? Actually, There are many stupid questions: "Should I drink this bleach?" Is just one example.
    Having said that, Just because it's a stupid question doesn't mean that it shouldn't be asked. It's better to know.

    A warm beer is better than a cold beer. Because nothing is better than a cold beer, and a warm beer is better than nothing.
