I love these guys!
They make pretty good aquarium fish. Hardy and fun to watch, but they're also picky eaters and somewhat secretive. The best foods for them are earthworms and other live foods and chunks of frozen shrimp, which you sometimes need to wiggle around on the end of a stick to get them to respond. They're close relatives of pikes and pickerels and like them are predators that respond to movement.
(They aren't native to my state, but i was lucky enough to come across an introduced population and have five. Also, here's an illustration of one I made a while back:)
A few of them seemed to like the flakes which I was rather surprised about. And nice drawing.
I added some panfish, which I believe are blue gill, and added some silver minnows as well. However the silver minnows I have kept for years.
