coldwater aggresive fish!

[corbypete]

is there such a thing?

i am planning on some bucktooth tetra, piranha, and pike but i wondered if there was anything as mean in the cold waters that may be of interest?

It depends what you mean by aggressive? There are fish that will consume anything that fits in their mouth, there are fish that will try to consume anything alive in their tank and then their are fish that will just kill anything and everything.

There are fish that are far more aggressive than the ones you have already chosen. But in coldwater terms, you'd be looking at some of the larger sunfish species for aggression. I hope you don't plan on keeping all these fish in the same tank?

lol no, two tanks of course


kidding

no im not, i have one tank, so one species...

 

[ryan]

Ok sounds good. What size is the tank? Maybe I can recommend some other fish you might like.

 

[corbypete]

I think kois are the agressive kind of coldwater fish. I remember one ate the eye of another years and years ago when my dad had a tank.

I've kept sunfish before, they have a tendency to sometimes get pissy and kill anything smaller than them... bait eels, bass, really big crayfish... There's a lot to choose from...

Chinese High fin banded sharks are agresive , sunfish bass and perch are too, but they stunt easily.
