Have had this pleco for about a year or two and think it's a female bristlenose, but I want to be absolute certain that I have the species correct and I didn't accidentally get a monster in waiting. Apologies for the reflections.

For comparison, here's the very obviously male albino bristlenose that shares the tank with her(?).

And btw, I've heard about bristlenose having aggression with their own kind if they don't have space, but these two are in a 125 gallon and I've not noticed any quarrels thus far.
