wow it's hard finding infor on keeping native fish in a tank..... well hopefully you guys can help me.... I want a fish that strikes minnows, worms, leaches like a bass.... hard and powerful, with some decent size(not 30 inches) I was gonna do Pbass but realized they are way tooooo big. So I wanted to try some natives. I am going to be using a 150 gallon and want to know what kind and how many ontario natives I can put in there???? like yellow perch, bluegill, pumkinseed and so on. Are they difficult to care for???? I have a 135 gallon discus tank and water changes daily on that tank is enough I don't want two like that..... what is a good species to keep and what is the best way to care for them... lastly do I basicly just remove heaters and just let the water be room temperature???
