I have a rat called Mad Max and at the moment he really is acting quite true to his name. He is a brown-hooded male and he just goes crazy all the time, like he's really hyper. This might calm him down a bit. He can be very aggressive with me, whimpering and grunting and trying to bite, especially when I try to pick him up. He will come to me if I sit on the floor or lay down so I can pet him.
Aggression is common in both male and female rabbits, especially during breeding season.
There isn't much you can do to correct it, other than avoiding situations in which he becomes particularly aggressive. If he is otherwise healthy, you could take him to a veterinarian experienced with rabbits to have him neutered. He should calm down, although it may take a few months after surgery to notice a real difference in his behavior.
