I definitely think it depends on the fish...But, I've got a 8" Red Devil, who I swear thinks he is the devil himself.
Started with 3. He killed the other two and everything else I've attempted to add to the the tank.
He'll ram and bite (you can her his teeth hit the glass) the glass when you walk by, jump out of the water and hit the hood. Tears up any plants, knocks large rocks around the tank, so much so that I removed them because I was afraid he would end up breaking the glass...SO, IMHO I would have to say the red devil
