The Most Aggressive Freshwater Aquarium Species

[Andrink]

snakehad in my opinion.

Snakeheads are an obvious one.

I haven't owned anything too aggressive but I did have a pair of Black Convicts and the male would attack my hand if I stuck it in the tank when he had eggs or fry.

If more people got ATF to large sizes I think wed be seeing more ATF maulings then most.. there's a video on YouTube I can't link to from my phone of a GATF ripping off the lower jaw of a black aro, aro wasn't too much smaller. Then there's the obvious hoplias, large channa, glarge territorial cichlids

So far from what I've had, my red wolf is the most aggressive. He bites at the gravel vac, bites at my hand if he feels like it, bites at tank mates if they get too close etc. Cichlid wise I haven't had much, but my male sp. Turquoise jewel beats the hell out of the other male in the tank a couple times a day. He gets beat on by my 3 bar Indo dat though

Indo datnoids are not aggressive usually.

 

[BuffaloPolypteridae]

Unless they get messed with, then they can take care of themselves

Really? They are also small for most large aquarium fish. Datnoids get small in captivity.

Datnoids are not as aggressive and not as much as a fighter than Jardini right?

Idk- I'd put my 17" indo with your Jardini and I'd love to see what happens. Most Dats are calm but then you get that occasional one that's very aggressive
