wow never knew a pleco could do that... loltydus;2252010; said:I've had bristle nose plecos in with my Pundamilia Nyerereis which are very similar to mbuna temperaments and they always fought. The bristle nose plecos held their grounds and actually roughed the nyererei up to the point where he stopped trying to bully the bristle nose. I actually had to take out the plecos since they were so aggro. Just my experience.
