Are their any aggressive minnows in il. I want to turn a 30 gallon in to a predator tank. I can only keep minnows or legal sized sport fish.

Shiners don't eat other full-grown fish, if that's what you mean by predator. They're all pretty aggressive in terms of trying to be the first to get to food though. Spotfin shiners come to mind in particular. Drop small garden worms in your tank and they'll never hit the bottom of the tank.

Depends on the shiner. If you mean shiner by any minnow. the larger chubs like creek chubs and fallfish will eagerly eat smaller fish.

As for minnow aggression, most minnows when with other minnows will chase each other trying to establish pecking order, then slow down the chasing a bit once established but never stop it. When they reach breeding condition they do get aggressive. But that depends on species, my western blacknose dace is almost always in breeding condition.

But when a more agressive species like a sunfish is added, minnows tend to school up tightly.

Aggression and predation are two very different aspects of fish behavior. Confusing the two makes for problems My Redfin Pickerel was among the most non-aggressive fish I've ever kept. But anything that fit in has mouth and moved, or after it was accustomed to captivity even hit the surface of the water was food and disappeared instantly. And then a Bluegill about half of its mass beat it to death.

I assume you mean big fast-moving minnows that can coexist in a tank with predatory fish. Depending on the size of your "predators" try Nocomis chubs (bluehead, hornyhead, river chub), creek chub, striped shiner, common shiner, blacknose dace, spotfin shiner, steelcolor shiner ...

Keep in mind that in the confines of an aquarium, any fish that fits in another fish's mouth will almost invariably wind up there.

Why can you only keep minnows and legal sized sport fish?

I assumed it was due to state regulations.

Can you keep fish that are not found in the state but are found in North America? That's how I legally keep and breed and sell my native fish, by picking species not found within state borders. My state regulates those the same as tropicals.

I do not know if I can but sent the question to the dnr. I mean fish that will eat feeder guppies.

My creek chubs have no issue eating small feeder fish but they are alittle on the large side for a 30 gal depending on how meny you put in it.

Creek and hornyhead chubs will eating smaller fishes no problems but they are too big for 30gal. Mudminnows and scuplins should be perfect for a 30gal.

Not sure what you are calling "hornyhead chubs" but if you mean Nocomis type chubs, then I do not agree that they eat fishes. I have kept bluehead chubs with very small fish for long periods of time with no problems.

Yes Nocomis type chubs with red spot near the eyes. The hornyhead chubs do indeed eating fishes. I've kept them with small fishes before and the small fishes kept disappearing. The hornyheads were fat and happy all times.

Seems that my Western blacknose dace is quite aggressive. He's killed 2 other shiners and is incessantly chasing 2 central stone roller minnows. Are the WBND always this aggressive? However, he knows well enough to leave my 2 juvenile sunnies alone.

Not always, but some are.  A bigger group of them (8+) might do better if you have enough space.
