would this work?

i didnt find a name but there are many fish in there

If they are all in the same ecosystem some are most likley 2ndary consumers, and there would be an apex predator. In other words some would be food for the others.
It would be fun to try all of them though (if you have a huge tank) and find out which species eats what and how. Eventually you would be left with only what would be the apex predator in the ecosystem, just under bears and birds

yea that would be awesome to watch

Let the battle begin!!! lol

 

[Mr.Geoff]

if you do that, leave out the smallmouth. those fish take too long to grow to size and dont need to be stuck in an aquarium death battle.

im not sure what ima do with the native yet but a death battle would be cool

 

[kzimmerman]

Not as much fun as you think. Fish would just dissapear.

 

[fhawk362]

Yea I was kidding, It wouldnt be an apparent death battle, and youll hear it from numerous fish keepers that often time oddball pairs work out, juvies stand a better chance, also tank size and layout (such as plenty of cover) helps in survival in such situations. I think you wont have too many problems though cause as I said before Ive had pretty good success with keeping juvies of species that others would say should not be together.

yea your probably right
