I understand that Buenos Aries tetra can get pretty big and they can be more aggressive than some others. You guys think they can be suitable in a large cichlid tank with medium sized cichlids like firemouth or convicts or jewels? Some guy at a LFS said they can get to 5" and can get pretty nasty and can and will scrap with small cichilds if they get attacked. I dont think he's right. He's making them sound like Exodons or something.
