This is your monster / predatory fish that rules the tank and must be all by itself. Any fish you put in there gets destroyed. The smaller one gets eaten and the big one gets killed.
For me, currently it is my Platinum Northern Snakehead and Striped Snakehead.
My Northern Snakehead does not want any tank mates. He decided to kill the Oscar that was with him for a month or so. But I saved it.
The only fish he didn't bother was the Pleco which I have located in a different tank now. And now the crayfish, he tried to bite it but decided it was strange and left it alone.
My Striped Snakehead is a total bad ass he has no mercy. Even the Pleco in his tank is beat up with torn fins.
