no , I thought about it but I'm too lazy for fish tanks now. when i was younger i was successful with dace and crayfish in a fish tank. The one above i got with a minnow net in central vt, it was acting weird for a fish and me and my buddy wanted to identify what it was. Ive caught sculpin as well but they require cold water i think. Even see many baby pike in the same area after breeding time. Like 3in long and they still hunt like the big ones do, kinda crazy to see a tiny pike hunt and kill a minnow, seen baby gar as well micro predators, very fun to watch.
