The Most Aggressive Freshwater Aquarium Species

  • We are currently upgrading MFK. thanks! -neo
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

My jar is 12 inches, its not winning. But the damage its jaws cause is big. You should have seen my clown knife all chewed up. But I really don't know, has your indo ripped a fish to the point where it has nearly no fins?
 
Ok I may be wrong sorry. But Jardini are aggressive. I can't put any new fish in my tank now. If I do, it gets mauled. I had 3 blue gouramis, 1 died, 2 are left at about 4 inches. My arowana has developed a relationship with them and does not attack them although they are tiny. I put in a similar sized yellow gourami and it got eaten straight away. So my arowana still does have friends.
 
yawn. this is the oldest topic discussed in the history of fish forums. it depends on the individual fish personality, ive had feeder goldies more aggressive then piranhas
 
Wolf fish. Hands down the most aggressive fish I've ever seen or owned.

i would kill any fish on here with my bare hands!-) my dads stronger and bigger... my cars faster... so childish but im a child lol... bullshark is the most aggressive freshwater fish of all, many reported human fatalitys. end of story...

these threads are started by people who want aggressive pets, these people should buy a black throat monitor lizard hands down the most aggressive thing ive ever kept a spore off satan... he whipped me in the eye with his tail, crapped on me and bit me locking on for ten minutes untile i eventually levered his mouth open with a pen...
 
Bull sharks are brackish fish right? Or do they just have the ability to survive for extended periods of time in freshwater?
