I definitely want to keep Natives and I would never release an aquarium fish into the wild. I will have a much larger tank within the next 3-6 months so if any of the fish grow too large I should have somewhere to put them.
And ok, I will check with the local DNR and see what I can find out about the collection of wild fish. As for tank decor, I intend to scour the woods/creek behind my house once the snow melts for anything interesting. Out of curiosity, what about purchasing shiners, shad, other baitfish from a local bait shop? Would this be recommended or would those fish pose too much of a disease threat? I just can't seem to find a good local source for native fish and with it being the middle of winter I'm open to ideas...
