Hey all I know this is a broad question with peoples experience's differing but I wanted to hear peoples opinions on which is the nastiest mbuna in the hobby thought it would be interesting to hear what some hobbyiststhink is the most aggressive thanks.
Ps. demasoni can be aggressive to their own, but usually are not so aggressive as to try and kill everything else in the tank.
Some of the Tropheops can be very aggressive, but aren't a common cichlid that people keep. Again, they are typically more aggressive towards their own kind, than random acts of killing.
M. lombardoi (kenyi), Melanochromis johanni andM. crabro can also be very aggressive, and towards all fish, not just their own kind.
Next up the ladder is Melanochromis auratus who can be terrors in the tank.
However, I'll agree with those who say Melanochromis chipokae are one of the most aggressive, if not the most aggressive mbuna available for the aquarium trade. They can be killers, and I had one grow to 8", and big at that. Some males can be downright nasty..
I think with the kenyi and crabro tank size has a lot to do with it. We keep ours in tanks with plenty of room for them to stretch out their legs and stake out a bit of tank for them selves and they are quite content.
Now with the melanchromis tank size does not matter, they are just nasty by nature. Some though are no problem at all while others are the devils spawn. Funny that.
