Is it normal for larger plecos to bully? No problems with the little one. But my larger pleco likes to swim around the bottom really fast and scare my cory's and other fish and then he goes to the spot i put algae wafers and runs everyone away and takes it by force and if anyone comes close he runs at them and hits them full on. Why is he such a jerk??? After this he always goes back and hides behind his favorite plant for the day.
