Put down which fish you think is the most aggressive in the freshwater aquarium. I would say Jardini.

Most aggressive fish ive ever owned , although pound for pound giant snakeheads or black wolfs have to be up there because of the teeth
Jardini are persistent though they never give up , mine was always on the hunt looking to hurt something ;)

My dad's old Red snakehead about 20 years ago named bomber. Lived in an old 240 gallon with poor filtration and algae. Probably ammonia and nitrite through the roof, I don't ever remember him doing a water change or filter cleaning. Ate only live food, mice, frogs, bass from the lake, insects, anything would get immediately destroyed. He even ate a battery that he later puked up once when a flashlight broke open above the tank during a power outage. That power outage, lasted 2 and a half days. He didn't miss a beat without filtration or heat. He was Satan spawn

Lol I havent seen one of these come up in a while. My most aggressive fish was my festae but only when I wasn't watching or when the tank lights were off. I never saw him do anything but when I get back or wake up there would be bodies or severely beat up guys.
