My Livingstonni male for my cichlid tank he is around 7-8"

My blue channel cat in my cat tank seems to be running things despite the tiger shovelnose which never moves lol... He is about 12"

In the community tank
My knight goby actually kind of odd.. But its a pretty weak tank as far as aggression.

Six years later, our Leonardo de Fishio is still boss of the tank. He bosses around Adonis, who is a bigger fish.

4" warmouth sunfish. Longear (approximately the same mass, but taller) thinks he's the boss, but he listens when the warmouth lays down the law.

Oscars in the Oscar tank, tho if they piss the cat off he has no prob shutting them up, say the male jag in the jag tank, but when the female wants to spawn she owns him. other oscar tank, just has the Oscar in it.
