The Most Aggressive Freshwater Aquarium Species

  • We are currently upgrading MFK. thanks! -neo
No auratus are nothing. I had 2 a while back in with 4 inch tinfoil barbs, bristlenose plecos etc. One turned black (meaning he was a male) and the other stayed yellow. They were 5 inches and ran scared from every other little cichlid i tried in the tank convicts, small GT, firemouths etc. When i put my clown knife in they were gone within an hour.

I say auratus because most on that thread said it was auratus

yes but they were all wrong. chipokae african cichlid pictures matched up much better. he was a terror, tho all fish have diff personalities
 
I was actually very surprised the first time I realised what a Jardini could do, as well as its aggression; I was in the lfs and the owner had a buttikoferi in a small tank, with a split down his face. He'd been fighting the jardini and stuck at him like a magnet despite the damage. Both were quite large.
 
I can't believe there is still a discussion! Pound for pound there is simply no other fish with such determined and intelligent aggression as a convict cichlid male. Other south American and African heavy weights, may have the size and homicidal tendency, but in terms of serial killer, sociopath type stuff, the convict cichlid takes it. They remind me very much of saltwater trigger fish.

i.e. Lets say you super size a convict with some sort of laser beam machine and it is suddenly a 15 inch fish. Name me a single other 15-20 inch fish that could survive its wrath?
 
^^Ehh...Dovi aka Wolf cichlid.
 
If you did super size a convict to 20", would it have teeth like a dovii? Quick question, I know it's off topic but how do you pronounce Dovii? Dovee or Dovi-eye?
 
I've always thought it was Dovi-eye due to the two i's but most of the time I pronounce it as Doe've eye.
